Doping effects on optical and conductive properties of titanium dioxide in terahertz range
Source abstract
Abstract
Abstract Terahertz time domain spectroscopy (THz-TDS) has been used to investigate the effect of bismuth doping on the refractive index, absorption coefficient, dielectric constant, and the conductivity of TiO2. Simple effective-medium approximation along with THz-TDS has been utilized for the extraction of these parameters from the composite samples. These values are increasing with dopant concentration. Moreover, the fitting of conductivity with Drude-smith model revealed that the charge carriers are localized and back scattering is the major conductivity mechanism.
