Webb1 okt. 1995 · A Monte Carlo simulation study is performed to determine the ratio γ/μ of the rate coefficient for bimolecular charge recombination and the charge carrier mobility … WebbThe paradox is that neither of these consequences of low mobilities is found in experiments on a-Si : H. Geminate recombination is essentially negligible near room temperature [5] , and estimates of the nongeminate, bimolecular recombination rate for electrons and holes are much lower than expected from the Langevin theory [6] .
