Photophysical properties of T1GaS2 layered single crystals

The alternating current photoconductivity (ac-PC) of TiGaS2 layered single crystals and the spectral distribution of the photocurrent is studied at different values of light intensity, applied voltage, and temperature. A continuous distribution of traps in the energy gap is presented by the values of the photoconductivity response time, which are reported from the light intensity dependence of ac-PC.
