OSCILLATORY BEHAVIOR OF THE H2O2 REDUCTION AT GAAS SEMICONDUCTOR ELECTRODES

Spontaneous current and potential oscillations during reduction of hyd rogen peroxide at GaAs semiconductor electrodes are described and disc ussed in the context of dynamical systems theory. The oscillations are shown to be accompanied by oscillations in the intensity of the elect roluminescence. The oscillatory behavior is discussed on the basis of existing models for the kinetics of the H2O2 reduction at semiconducto r electrodes.
