Abstract

We introduce the pulsed ruby laser as a new tool for homogenous accelerated degradation of a-Si:H and discuss in detail the sample temperature during the ruby pulse and the value of the saturated density of states (DOS), achieved by this laser. The degradation dynamics and the saturated values of the DOS and electrical room temperature conductivity (σRT) are presented on a set of different undoped a-Si:H samples. It is illustrated that there is no correlation between the initial and light-saturated DOS, which is determined in addition to the H content and the a-Si:H microstructure indirectly also by impurities. © 1993.
