AbstractWe demonstrated a novel and widely accessible method for determining the electron and time of with different by combining with Hall measurement. The transmission spectra (0.1–2THz) were well described by Drude model. It is found that electron varied from 0.23to 0.26as the electron concentration changes from 5.9 × 1017 cm−3 to 4.0 × 1019 cm−3. The dependent characteristic is ascribed to the non-parabolicity of conduction band. Free carrier localization mechanism explained the discrepancy in obtained from and Hall measurements.
This study was performed using TeraView's TPS Spectra 3000 system. (TeraView, Cambridge, UK)
