Organic and inorganic nanostructures for optoelectronic devices

Abstract

Nanostructures have been attracting lots of attention both for fundamental physics studies as well as applications in photonics, renewable energies, and sensing. A great variety of different nanosized materials have been synthesized up to date. Among different materials, various metal oxides, such as ZnO, TiO2, CuO etc., are of interest for applications in optoelectronic devices. Metal oxide semiconductors can be fabricated by vapor deposition or chemical synthesis methods. In this work, we present ZnO nanostructures fabricated by different methods. Then we focus on the fabrication and characterization of ZnO nanorods fabricated by a hydrothermal method on different substrates. ZnO nanorods fabricated by hydrothermal method are of particular interest for application in hybrid organic/inorganic devices due to low fabrication temperature. We also present fabrication and characterization of organic nanowires consisting of a commonly used material, tris (8-hydroxyquinoline) aluminum. The device implications of using organic micro- and nanostructures in devices are discussed. ©2007 Old City Publishing, Inc.
