Yq. Gao et Ra. Marcus, On the theory of electron transfer reactions at semiconductor/liquid interfaces. II. A free electron model, J CHEM PHYS, 113(15), 2000, pp. 6351-6360
Electron transfer reactions at semiconductor/liquid interfaces are studied
using the Fermi Golden rule and a free electron model for the semiconductor
and the redox molecule. Bardeen's method is adapted to calculate the coupl
ing matrix element between the molecular and semiconductor electronic state
s where the effective electron mass in the semiconductor need not equal the
actual electron mass. The calculated maximum electron transfer rate consta
nts are compared with the experimental results as well as with the theoreti
cal results obtained in Part I using tight-binding calculations. The result
s, which are analytic for an s-electron in the redox agent and reduced to a
quadrature for p(z)- and d(z)(2)-electrons, add to the insight of the earl
ier calculations. (C) 2000 American Institute of Physics. [S0021-9606(00)70
