Influencing Factor of Photoelectron Fluctuate in Crystals

LI Xin-zheng,ZHENG Bin (College of Sciences, Hebei University of Science and Technology, Shijiazhuang 050054, China)  
Based on the photoelectron character, the factor effecting on the creation of photoelectron was analyzed in light absorption excitation and thermal excitation. The effect of different electron traps was different at electron decay in crystals. The shallow electron traps made the elec- tron decay slowly because that they prolonged the relaxation time of electron in conduction band. The deep electron traps accelerated the electron decay because of the strong bonding or deep elec- tron trap as recombination center.
