    Abstract

    Superlattice type photodiodes of a GaAs-AlXGa1-XAs structure were studied at room temperature. A combination of potential-well width and barrier width was sensitive to the charge multiplication factor. Using a diode of 10nm well and 15nm barrier, the detector characteristics were investigated from a point of view of achieving a high gain. This type of photodiodes was confirmed to be sensitive to Cherenkov light generated in water. Effects of carrier doping up to 1018cm-3 at room temperature on the multiplication rate is discussed.
