2020 45th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).
Tuning of optical and conductive properties of a material is key parameter for device fabrication in THz technology. We have demonstrated the enhancement of these properties of titanium dioxide (TiO2) with the doping of antimony and bismuth in spectr
