Photo-Hall Characterization of Semiconductor Matrices with Disordered Particulates.

摘要

1 Mobility of Carriers in LTG-GaAs: GaAs epilayers containing arsenic precipitates are semi-insulating because of a lack of carriers. Therefore a direct measurement cannot be made of the mobility. When these materials are used as photoconductors. light produces electron-hole pairs. (2) Large-Area. High-Speed Photodetector: Recently, large-area photodetectors have become very important in high-speed fiber communications. Large area detectors are essential to the success of plastic-fiber optical networks.
