Development of Flexible Nanocomposite Hybrid Aero-Materials

Irina Plesco

 

The project is targeted on the development of new semiconductor and hybrid aero-materials, complex study of their properties and finding of suitable applications for them. During the project aero-ZnS and mixed phase aero-ZnS/ZnO hollow tetrapodal networks have been obtained in the template assisted HVPE processes. Graphitic aerogels were employed in the process of growth of distributed nanoparticles and nanowires of CdS, CdTe and InP by the magnetron sputtering technique, and of InP and ZnS by the HVPE method.

The resulting novel materials and nanostructures were characterized by means of electron microscopy, optical spectroscopy, electrical testing under illumination and application of mechanical stress. The carbon aerogel decorated with a nanocrystalline semiconductor layer showed to be sensitive to hydrostatic pressure, at the same time 3D interconnected networks of aerographite functionalized with semiconductor nanoparticles show high flexibility under uniaxial mechanical stress.
