Abstract:

Project "1D and 2D ZnO based nanostructures and innovative processes for direct integration in gas sensing devices and UV radiation detection” having acronym NANOZON, is in line with research direction 1.7 Nanoelectronics, photonics and micro / nano integrated systems. The whole concept behind NANOZON project is focused on development of 1D and 2D ZnO based nanostructure and on using their properties in order to obtain gas sensing and UV radiation detectors devices having superior performances. The fabrication of experimental gas sensor models and UV detectors at micro/nano scale, will be based on the development of innovative processes for obtaining ZnO nanostructures (1D and 2D) and zinc oxide nanoporous layers that are to be directly integrated into sensor structures. 1D and 2D ZnO nanostructures (nanowires, interconnected nanowire networks, nanowalls) and nanoporous layers that will be used in sensing devices, will be prepared by using innovative processes that will be developed in the project framework, starting from aqueous solution (Hydrothermal process ) and from thermal oxidation of zinc metallic layer. In order to increase the sensitivity and selectivity of the corresponding sensors the resulting ZnO nanostructures will be functionalized with metal nanoparticles and/or carbon nanodots . In order to obtain the sensors the resulting nanostructures will be integrated using a combination of two approchess - "bottom-up" (growth and self-assembly in solution of the nanostructures) and "top-down" (sellective/localised growth at micro/nano scale by using patterned substrates). The following two major improvements result by integrating ZnO nanostructures in the sensors: i) increasing the active surface area, which is the one exposed to gas ( two orders of magnitude for nanowires having an aspect ratio > 20) resulting in increased sensitivity, ii) a decrease of the operating temperature (room temperature up to 200 ⁰C maximum) by comparing with ZnO thin films based sensors (400-600 ⁰C). Research activities needed in order to meet the project goals are grouped into five work packages: WP1- Growth from aqueous solution of one-and two-dimensional ZnO nanostructures with controlled morphology on various substrates (P1/UDJG); WP2 - Innovative processes to obtain porous ZnO layers by using thermal oxidation of zinc metal layers (CO); WP3 – Complex characterisation, structural, morphological, electrical and optical of the synthesized and the functionalized ZnO nanostructures (CO); WP4-innovative processes for direct integration of ZnO nanostructures into micro/nano scale devices. Fabrication of experimental models of gas sensing structures and UV radiation detectors (CO, P1, P2, P3); WP5 - Design and fabrication of the electronic platform for functional characterization of sensors (P2, P3). In order to implement these activities a consortium of 4 partners with expertise and complementary facilities was constituted: 1 national institute - IMT Buc. with the role of CO, a university – University " Dunarea de Jos’’ Galati ( P1) and 2 co-financing SMEs, having research and development activities in the field of sensors, P2/SELETRON and P3/APEL LASER. The expected results and the project contribution are the following: optimized processes for the growth of 1D and 2D nanostructures and for porous zinc oxide layers; innovative process for nanostructures direct integration in sensing devices; methods for the characterization of the nanostructures and functionalized nanostructures, experimental models of gas sensors and UV detectors; published papers; communications at national and international conferences.
