Nanostructured Cr Doped CdO Thin Films For Optoelectronic Devices

Transparent conducting oxides (TCOs) such as pure and doped cadmium oxide have attracted much attention owing to their potential applications in opto-electronic device technology. In particular CdO based TCOs are of great interest due to their metal like charge transport behaviour with an exceptionally large carrier mobility and good optical transparency in the visible region. It''s high electrical conductivity and optical transmittance in the visible region of the solar spectrum along with a moderate refractive index makes it useful for various applications such as photovoltaic solar cells transparent electrodes gas sensors liquid crystal display photodiodes photo-transistors and optoelectronic devices. In this book the optimized deposition conditions for the preparation of Cr doped CdO thin films structural surface morphological electrical and optical properties of the thin films were reported systematically. The promising approach for the preparation of high-quality thin films for its applications in optoelectronic devices will discussed clearly in this book.
