    • A photoconductive layer of an electrophotographic photoreceptor has a super lattice structure obtained by alternately stacking thin layers (the thickness falls within the range of 30 to 200 .ANG.) of at least two types of amorphous semiconductors having different optical band gaps. In the super lattice structure, when the layer having a narrow bandgap is sandwiched between the layers having wide bandgaps, a quantum well is formed. By the quantum effect, electrons in the well are shifted to cause high mobility of carriers. When the super lattice structure is applied to the photoconductive layer of the electrophotographic photoreceptor, the number of carriers generated at the interface between the thin layers is large. In the photoconductive layer having the super lattice structure, carrier lifetime is prolonged, in the potential well layer, 5 to 10 times that in a single layer, due to the quantum size effect, as compared with that of a single layer, thereby increasing light sensitivity of the photoconductive layer.
    • 电子照相感光体的光电导层具有通过交替层叠具有不同光学带隙的至少两种类型的非晶半导体的薄层(厚度在30至200范围内)而获得的超晶格结构。 在超晶格结构中,当具有窄带隙的层夹在具有宽带隙的层之间时,形成量子阱。 通过量子效应,阱中的电子被移动以引起载流子的高迁移率。 当将超晶格结构施加到电子照相感光体的光电导层时,在薄层之间的界面处产生的载流子数量大。 在具有超晶格结构的光电导层中,与单层相比,由于量子尺寸效应,在电位阱层中,载流子寿命在单层中延长了5〜10倍,因此增加了光 光电导层的灵敏度。
