Description

Time-resolved photoinduced absorption (PIA) and steady-state photoconductivity (PC) experiments are used to study recombination processes in electron-irradiated hydrogenated amorphous silicon (a-Si:H). Defect densities measured by ESR range from 5 x 1015/cm3 to 1018/cm3. It is found that while increasing the dangling-bond density reduces the PC, the PIA decay rate increases. The results are discussed in the context of a recombination model where the defect density determines whether the carriers recombine through a fast bimolecular or a slower monomolecular process
