Photoconductivity applications
WebPhotoconductivity, as a well-known optical and electrical phenomenon in semiconductor, is an effect that the electrical conductivity increases due to the absorption of light radiation (Bube, 1960, 1992; Rose, 1963). Several mechanisms, such as the absorption of the incident light, the generation of the electron–hole pairs, and the carrier ... WebThe nonequilibrium carrier dynamics and its temperature dependence in MoTe2 are of prime importance, which sheds light on understanding the anomalous optical response. Here, we employ transient terahertz (THz) spectroscopy to study the temperature-dependent photocarrier dynamics in MoTe2 films. After photoexcitation at 1.59 eV, 1T’-phase MoTe2 …
