ANALYSIS OF CURRENT POTENTIAL CHARACTERISTICS AT N-TYPE AND P-TYPE SEMICONDUCTOR ELECTRODES

The kinetics of charge transfer processes at semiconductor electrodes have been investigated by quantitative evaluation of current-potential curves. Studies of various redox reactions have shown that these processes can be kinetically or diffusion controlled depending on the relative position of standard potential of the redox system and the corresponding energy band of the semiconductor. The quasi-Fermi level concept has been applied to compare quantitatively majority carrier processes at n-type electrodes.
