Abstract
The luminescence decay of a‐Si:H films is found to be strongly dependent on the sample thickness and on the penetration depth of the exciting light: the decay becomes faster for excitation close to the surface, and when the sample thickness is reduced. We suggest that these effects are due to surface electric fields.Keywords
