Abstract:

Electronics is nowadays among the most demanded technologies for the accelerated development of the digital world. The enhanced need of efficient functionalities and multifunctionalities of electronic devices enhances the interest for new materials and systems that are cheap, sustainable and which can operate with a low power consumption and moreover, are recyclable or degradable materials, in order to reduce the electronic waste. With the boom of graphene, new 2D van der Waals materials are fulfilling the above criteria and are reaping attention due to an enormous spectrum for novel applications in electronics, photonics, spintronics, secure information storage and communication, catalysis, bioelectronics, sensing, energy storage and conversion. In this project, the focus is directed on the development of advanced strategies of chemical and physical surface manipulation, such as adsorption and/or doping with adatoms or organic molecules, application of local electric, mechanic and magnetic stimuli for activating and controlling the structure and the related electronic, magnetic and spintronic properties of new 2D materials and in hybrid heterostructures. The investigations will follow the path of control and performance from a microscopic approach at single functional level, with atomic and molecular resolution, to proximity effects and collective electronic, magnetic and spin-transport behavior in single 2D layers, multilayers, hybrid 2D and/or intercalated systems.

Abstract:

GlassyMEM aims to accelerate the discovery of chalcogenide glasses for memristor applications through the use of machine learning methods. Chalcogenide phase change materials possess excellent electrical properties, including high resistivity contrast between glass and crystalline states and dynamic resistance tuning, making them ideal for memristors in AI, big data, and IoT applications. Traditional approaches for identifying new chalcogenide glasses rely on empirical rules, lacking a universal predictor of glass formation ability (GFA).

In this project, we will construct a comprehensive database integrating literature and experimental data obtained within this project. Chalcogenide libraries will be synthesized via magnetron co-sputtering, and their structural and compositional properties will be extensively characterized. Machine learning models will be developed and trained to predict GFA for chalcogenides, enabling faster and more efficient material screening.

Furthermore, the electrical properties of the most promising candidates will be investigated for memristor applications, aiming to achieve more powerful, energy-efficient, scalable, and cost-effective memristor devices. By adopting a data-driven approach, GlassyMEM will contribute to a deeper understanding of GFA, reducing costs, risks, and time associated with conventional methods. The project will propose viable candidates for advanced memristor technologies.

Abstract:

LIGHTCELL ims at developing innovative architectures for thin-film photovoltaics (TF-PV) utilizing inorganic, environmentally stable (Sb2X3, X=S, Se) materials and sustainable fabrication processes with reduced energy consumption. Sb2X3 can be synthesized in a quasi-one-dimensional (quasi-1D) form, addressing the main factors limiting the efficiency of TF-PV, i.e., recombination of the photogenerated carriers at the grain boundaries. A multidisciplinary consortium of academic and industrial partners aims at developing a scalable technology of sustainable, cost-efficient, and lightweight PV. For faster feedback loop to synthesis, a new tool for the rapid and non-destructive mapping of 2D and 3D crystallographic orientation of quasi-1D materials will be developed. The PV technology developed in LIGHTCELL will be validated in demonstrators by the industrial partners, targeting lightweight building-integrated PV applications, contributing to sustainable green energy production.

Abstract:

The main objective of the project is to obtain ferroelectric materials with controlled electronic properties at the same level as this properties are controlled in Si. This will be realized by hetero-valent doping, correlated with stress engineering and band gap engineering without affecting, as much as possible, the ferroelectric properties. The main objective is complex and ambitious because, up to date, there was no experimental demonstration that it possible to obtain n or/and p type conduction in epitaxial ferroelectrics. The successful achievement of this objective will open a new domain, that of ferroelectric electronics or ferrotronics, by producing electronic devices of p-n homo-junction type or junction transistors with ferroelectric materials. Two types of materials are envisaged, namely lead titanate-zirconate (PZT with tetragonal structure and a mixed bismuth ferrite (BFO) with bismuth chromit (BCO). In the first case the heterovalent doping will be studied on Pb or Zr/Ti sites with the aim to obtain n and p type conduction. The final goal is to produce a p-n homo-junction based on epitaxial PZT films. In the second case band gap engineering will be tested by varying the Fe/Cr content, and the dominant conduction mechanism will be identified, the goal being to use the material in photovoltaic applications. The activities will contain: theoretical studies regarding the relation between dopants, electronic properties and the ferroelectricity, including self-doping effects or electrostatic doping; target preparation for deposition of thin films; epitaxial growth of the film; characterization activities of the structure and physical properties. Not only classic doping in the target is envisaged but also doping during the epitaxial growth. The consortium is composed of 4 teams from three different institutions, including a number of 14 young researchers full time equivalent.

Abstract:

Last decades brought a considerable development of technologies based on ordered systems. Starting with semiconductor physics and photovoltaics, technologies soon evolved towards the utilisation on large scale of thin films and of surface / interface properties. Example go nowadays from data storage and readout (electrostatic or magnetic memories, giant magnetoresistance) to catalysis, gas sensors or photocatalysis (surface phenomena), and towards interfaces with biological matter (biosensors, templates for tissue reconstruction, interfaces between biological electrical signals and microelectronics). In Romania, crystal growth is performed since half a century; nevertheless, during the last years these activities fade out and need to be seriously reinforced, especially with the advent of new laser and detector technologies required by the Extreme Light Infrastructure facilities. Also, surface science started to be developped seriously only during the last decade, together with techniques involving self-organized nanoparticles, nanoparticle production etc. The main goal of this Project is to gather the relevant experience from the five partners, namely the experience in crystal growth from the University of Timișoara, with the surface science, nanoparticle and nanowire technologies developped by NI of Materials Physics, the cryogenic and ultrahigh vacuum techniques provided by the NI for Cryogenic and Isotopic Technologie, and the experience in ordered 2D systems (graphene and the like) owned by the NI for Microtechnologies (IMT). This common agenda will result in a coherent fostering of technologies relying on ordered systems of variable dimensionalities: 0D i.e. clusters or nanoparticles, including quantum dots; 1D i.e. free and supported nanowires and nanofibers; 2D: surfaces, interfaces and graphene-like systems; and 3D crystals of actual technological interest, together with setting up new ultrahigh vacuum, surface science and electron spectroscopy techniques.

Abstract:

The development of complex nanocomposite materials consisting of different matrices (polymer-like, oxides, intermetallics, liquids) functionalized by different nasnostructured additions (carbon allotropes, magnetic nanoparticles with different organizations, nanostructured semiconductors, etc.) is the aim of this project. The unique combinations of interacting nanophases offeres to the hybrid nanocomposite material new or enhanced proprieties of high interest for applications. In this context, according to the previous experience of the involved teams, the complex project (formed by 4 component projects) is focused on the development of new optimized nanocomposite systems to be included in experimental demonstrators or final products to be transferred to economical companies. The project will contribute both to an increased scientific visibility of the partners as well as to enhancing the institutional performances by the development of new technical and scientific capacities.

Abstract:

This Project is concentrated on a detailed study of the intimate processes occurring when molecules are adsorbed, desorbed or are reacting at atomically clean, well characterized, single crystal ferroelectric surfaces synthesized by pulsed laser deposition (PLD). In situ investigations will be carried out by a multitude of surface science techniques: X-ray photoelectron spectroscopy, X-ray photoelectron diffraction, low energy and reflection high energy electron diffraction (LEED and RHEED), mass spectroscopy, aiming to seek adsorptions, desorptions and molecular reactions when the ferroelectric polarization is triggered by external parameters (optically, thermally or by charge carrier injection). The goal of this project will be a detailed description of the molecular processes occurring at ferroelectric surfaces (lead zirco-titanate and barium titanate, also combined with noble metals as co-catalysts – Ag, Au, Pt, Pd), mainly involving molecular reactions of actual interest for automotive industry: (i) oxidation of carbon monoxide; (ii) reduction of nitric or nitrous oxide (NOx); (iii) combined reaction pathways for three way catalysts. The results of the Project will be helpful for the development of new catalytic converters, cheaper, operating at lower temperatures and whose activity may be triggered optically or electrically. The main output will consist in scientific papers in top tier ISI journals and possibly a patent application towards the end of the Project.
