  • Abstract In this thesis we have performed detailed study on THz transmission through m-plane ZnO on m-plane sapphire substrate. We have studied the frequency dependent optical properties for annealed and unannealed non polar ZnO for a- and c-axis. The refractive indices and extinction coefficients of m-plane ZnO at THz range are reported. The carrier concentration and mobility determined using THz-TDS method show good agreement with simple Drude model. For annealed and unannealed m-plane ZnO we observed a significant difference for all the above mentioned optical properties. It is found that, for annealed ZnO, carrier concentration and mobility is larger than that of the unannealed ZnO.
