Abstract: Abstract The main factors of the laser scanning in-situ photoelectrochemical microscopicmeasurement system which is set up in our lab have been discusaed in this paper. Some applications ofthis technique for insttn study of medificiition and processing of semiconductor electrodes , monitoringof electredeposition process of semiconducting material and redox reaction occurring at metal oxideelectrodes have aiso been presented. The results have shown that the technique is very powerfui thatfor studing local photoelectrochemical properties of semiconductors and metal oxide electredes. Theseprovide important information on the micro structural and electronic properties in the solidlelectrolyteinterface.AbstractLaser scanning, Local photocurrent spectroscopy, Photoelectrochemical,Semiconductor electode
