摘要

提出了一种包含具有复杂势分布的宽量子阱级联的有源区域中量子跃迁的谱参数和振子强度的量子理论。利用这种阱和势垒的不对称排列，计算并提出了一种新的级联空间设计，在没有施加电偏置的情况下，振荡强度的大小相当大，并且观察到电子的单向共振隧穿输运。因此，有可能确保宽带光电探测器在远红外范围内的成功运作。

Spectral properties of a broadband far infrared photodetector with a new design of active region

A quantum theory of spectral parameters and oscillator strengths of quantum transitions in an active region, which contains cascades of wide quantum wells with a complicated potential profile is developed. A new spatial design of the cascade is calculated and proposed with such an asymmetric arrangement of the wells and barriers, in which, without an applied electric bias, the magnitudes of oscillator strengths are considerable and one-way resonant-tunneling transport of electrons is observed. As a result, it becomes possible to ensure a successful functioning of the broadband photodetector in the far IR range.
