摘要： A semiconductor photodetector may provide charge carrier avalanche multiplication at high field regions of a semiconductor material layer. A semiconductor current amplifier may provide current amplification by impact ionization near a high field region. A plurality of metal electrodes are formed on a surface of a semiconductor material layer and electrically biased to produce a non-uniform high electric field in which the high electric field strength accelerates avalanche electron-hole pair generation, which is employed as an effective avalanche multiplication photodetection mechanism or as an avalanche impact ionization current amplification mechanism.
