    • The invention provides an avalanche photodiode multilayer structure comprising an absorption layer for absorbing photons and subsequent generation of electron hole pairs, a field relaxation layer in contact with the absorption layer and a multiplication layer in contact with the field relaxation layer. The multiplication layer comprises a plurality of periods of first and second layers. The first layer has a first graded energy band gap being gradually widen in a direction toward which electrons are accelerated by a predetermined electric field. The second layer has a second graded energy band gap gradually narrowing in the direction. Both a conduction band edge and a valance band edge are free from any discontinuity and sloped down toward the direction through the first and second layers when the first and second layers are applied with the electric field.
    • 本发明提供了一种雪崩光电二极管多层结构,其包括用于吸收光子和随后产生电子空穴对的吸收层,与吸收层接触的场弛豫层和与场弛豫层接触的倍增层。 乘法层包括多个第一和第二层的周期。 第一层具有在电子加速预定方向的方向上逐渐变宽的第一渐变能带隙。 第二层具有在方向上逐渐变窄的第二梯度能带隙。 当第一和第二层被施加电场时,传导带边缘和价带边缘都不会有任何不连续性并且朝向穿过第一和第二层的方向倾斜。
