    • Described is a semiconductor photo detector comprising, between two electrodes, at least one of said electrodes being a transparent electrode, an optical absorption layer which is composed of a non-single crystalline material, absorbs light and generates photo carriers and a carrier multiplication layer which is composed of a non-single crystalline material and multiplies the photo carriers generated by the optical absorption layer. The carrier multiplication layer is formed of a multilayer film obtained by stacking films each having plural layers which are composed of non-single crystalline Zn.sub.x Cd.sub.1-x M (0.ltoreq.x.ltoreq.1, M represents one selected from the group consisting of S, Se and Te) and are different in a composition ratio in accordance with a change in the value of x in said Zn.sub.x Cd.sub.1-x M, whereby a band discontinuity .DELTA.Ec of the conduction band can be made larger, an ionization rate of electrons can be heightened and the place where ionization occurs can be specified. As a result, sensitivity increase, noise reduction and low voltage drive can be attained.
    • 描述了一种半导体光电检测器,其包括在两个电极之间,所述电极中的至少一个为透明电极,由非单晶材料构成的光吸收层吸收光并产生光载流子,载流子倍增层 由非单晶材料构成,并将由光吸收层产生的光载体相乘。 载体倍增层由多层膜形成,该多层膜是通过层叠由多层构成的非单晶Zn xCd 1-x M(0≤x≤1,M表示选自S ,Se和Te),并且根据所述ZnxCd1-xM中的x的值的变化,组成比不同,由此可以使导带的带不连续性DELTA Ec更大,电子的离子化速率可以 可以指定电离发生的地方。 结果,可以实现灵敏度增加,降噪和低电压驱动。
