The origin of persistent photoconductivity in amorphous silicon

Research output: Contribution to journalArticlepeer-review

10 Scopus citations


The persistent photoconductivity (PPC) effect in doping modulated amorphous silicon multilayers can result from the thermal equilibration of the defect structure in the doped a-Si:H layers. The magnitude, exposure and doping dependence of the PPC effect can be accounted for using the thermal equilibrium model.
