S. Gosavi et al., Temperature dependence of the electronic factor in the nonadiabatic electron transfer at metal and semiconductor electrodes, J ELEC CHEM, 500(1-2), 2001, pp. 71-77
The temperature dependence of the electronic contribution to the nonadiabat
ic electron transfer rate constant (k(ET)) at metal electrodes is discussed
. It is found in these calculations that this contribution is proportional
to the absolute temperature T. A simple interpretation is given. We also co
nsider the nonadiabatic rate constant for electron transfer at a semiconduc
tor electrode. Under conditions for the maximum rate constant, the electron
ic contribution is also estimated to be proportional to T, but for differen
t reasons than in the case of metals (Boltzmann statistics and transfer at
the conduction band edge for the semiconductor versus Fermi-Dirac statistic
s and transfer at the Fermi level, which is far from the band edge, of the
metal). (C) 2001 Elsevier Science B.V. All rights reserved.
