Abstract
Electromagnet ic wave falling on solid surface acts on the medium with a force. This force brings about a redistribution of surface charges and the surface potential is varied. By measuring this potential variations, the surface electrical properties on conductors, semicionductors and dielectrics can be tested. In this paper, two dimensional photocharge voltage on the
