Photoinduced Current Transient Spectroscopy of TlInS2 Layered Crystals Doped with Er, B, and Tb Impurities

Abstract

Photoinduced current transient spectroscopy (PICTS) has been utilized to study electrically active defects in TlInS2 single crystals doped with Er, B, and Tb. Eight traps with activation energies lying in between 0.21 to 0.55 eV have been detected. The origin of these traps is discussed. (C) 2011 The Japan Society of Applied Physics
