Two-dimensional current/voltage measurements of reverse-biased n/sup +/-diodes by photoemission

Two-dimensional (2-D) current/voltage distributions of avalanche-breakdown n/sup +/-diodes are discussed by comparing 2-D photoemission-intensity distributions with electrical measurements. It was found that total photoemission-intensities were proportional to the avalanche-breakdown currents, and 2-D current/voltage distributions can be estimated by analyzing 2-D images of photoemission-intensities.<
