摘要

Metastabilities in lithium-doped a-Si:H films are studied after fast quenching from high temperatures (FQ) as well as after exposing to visible light (LS). We have studied the relaxation of a new FQ + LS state obtained by light soaking a-Si:H films in FQ state. We find that FQ + LS state is also metastable; however, in this case the isothermal relaxation does not follow a stretched exponential. Further, the relaxation of conductivity in FQ + LS state can be explained, if the return of the Fermi level from this state to the state obtained after slow cooling is taken to be the sum of the relaxations of Fermi levels in the FQ and LS states. This suggests that FQ and LS are independent. (C) 1998 Elsevier Science B.V. All rights reserved. [References: 9]
