Abstract

A specially designed photoconductivity experiment directly shows that, above room temperature, the steady-state recombination lifetime of the free electrons in undoped amorphous silicon can be described by the free electron quasi-Fermi energy alone. The apparent discrepancy on recombination demarcation levels between the Rose model and the Simmons-Taylor model is resolved by including the effect of the occupation function. The significance of the free electron quasi-Fermi level is discussed.

This work investigated the recombination lifetime vs. the temperature as the free electron quasi-Fermi level was fixed in phosphorous doped a-Si:H. Their data at low temperatures do not agree with Eq. (4) due to the non-negligible contribution of the tunneling between the gap states. Their data in the temperature region of the present work are inconclusive due to a calculation error (private communication with H. Fritzsche).CrossRefGoogle Scholar

[14]. The advantages of using undoped samples include the following: (1) EF- EF does not shift much with temperature and can be used as a reference energy; (2) EFn - EF is large enough under normal light intensity without introducing light-induced defects which will change the sample during the measurement.Google Scholar
[15]. The band to band recombination rate is much smaller than the recombination rate through the gap states, due to a high density of the gap states in a-Si:H. The hopping rate between the gap states is also much smaller than the rates considered here because the temperature is high. (Ref. 1)Google Scholar
