Lifetimes of radiative recombination of geminate and non-geminate pairs in amorphous semiconductors are calculated at thermal equilibrium. The theory is applied to calculate the radiative lifetimes of type I and II geminate pairs and non-geminate pairs in hydrogenated amorphous germanium (a-Ge:H) and compared with the experimental results. The type II geminate pairs can exist in singlet and triplet spin states, only singlet is considered here, whereas the type I geminate pairs do not have spin dependence. � 2006 WILEY-VCH Verlag GmbH & Co.
