H. Gleskova et al., ISOLATING THE RATE OF LIGHT-INDUCED ANNEALING OF THE DANGLING-BOND DEFECTS IN A-SI-H, Journal of non-crystalline solids, 166, 1993, pp. 183-186
The results of a study of the kinetics of the light-induced annealing
of defects in hydrogenated amorphous silicon (a-Si:H) at the temperatu
re of 125 degrees C are presented. The rate of removal of the metastab
le defects and the final steady-state defect density both increase wit
h light intensity. The functional dependence of the light-induced anne
aling term on the light intensity, or carrier generation rate G, is pr
oportional to G(0.66-0.84), and thus is proportional to the density of
the photo-generated carriers.
