Effect of Titanium Doping on the Electrical Properties of Conducting ZnO Transparent Thin Films

Abstract

ZnO transparent conductive thin films are the most prominent substitute materials in the development of Ti-oxide thin films. Zinc oxide is a unique material that exhibits dual properties; semiconducting and piezoelectric. In this paper,a comprehensive study of crystalline size using X-Ray diffraction patterns and TEM images of Ti-doped ZnO with nano TiO2 in rutile phase is made to understand the development and growth of nano devices. ZnO has higher excitation binding energy approximately 60 MeV which is multifunctional and can be utilized in the field of ferroelectric, ferromagnetic and piezoelectric materials.Ti-doped ZnO-based semiconductors and nanowire devices are also of great importance for the integration on a single chip. ZnO nanomaterials can also be applied for biosensors, UV detectors etc. Ti-doped ZnO shows ferromagnetic behavior at room temperature. Also a reviewed is done on the recent activities and progress of ZnO nanomaterial with the brief discussion of applications of ZnO low dimensional structure. Using chemical bath deposition (CBD) technique, Ti-doped ZnO thin films are successfully synthesized. The crystalline size is determined by X-ray diffraction. For the analysis of surface morphology, TEM is used. The dielectric properties and electrical conductivity of the synthesized film are analyzed at different temperature and frequencies
