Abstract

A small, simple, robust, compact and low-cost optical beam-induced current (OBIC) microscope is built with a laser diode (LD) as a light source. Dependence of the OBIC signal on LD power and LD case temperature, which is related to LD wavelength, are determined. The axial and lateral responses of OBIC microscope are also obtained and compared with that of the confocal reflectance microscope. Combining the OBIC and confocal reflectance imaging modes the microscope can discriminate microscopic semiconductor and metallic regions.
