Ag. Sarkisyan et al., IMPEDANCE OF THE ELECTROCHEMICAL-CELL WITH A TITANIUM-DOPED FE2O3 SEMICONDUCTOR ELECTRODE, Russian journal of electrochemistry, 33(7), 1997, pp. 753-756
The frequency dependence of the impedance of an electrochemical cell w
ith a semiconductor electrode based on titanium-doped Fe2O3 is studied
. An equivalent circuit is selected and the capacitance of the space c
harge region in the semiconductor is calculated. The slow diffusion of
charge carriers is shown to be the limiting stage of the electrode pr
ocess.
