摘要：

Intrinsic a-SiC:H films with optical bandgaps E(g) less-than-or-equal-to 2.0 eV have been optimized with respect to minimum PDS Urbach energy E0. We demonstrate that the increasing density of midgap defects induced by C incorporation controls AM1 photoconductivity at room temperature whereas the low temperature photoconductivity is governed by additionally generated conduction band tail states.
