摘要：

The electronic properties of electrochemically formed oxide layers on aluminium-manganese alloys have been studied using excimer laser excitation for photocurrent and photovoltage measurements in both borate-boric acid buffer and diluted sulphuric acid solutions. At constant anodizing conditions for the growth of the surface oxide layers, the photoelectrochemical measurements at 308 nm (XeCl-line) exhibit positive and negative photocurrents depending on the applied potential. They also show photovoltages of both signs under galvanostatic perturbation conditions.
