摘要

本文通过模拟光吸收，对基于GaAs/Al0.20 Ga0.80As材料体系的光探测器进行了简要的研究，通过详细计算与价带和导带相关的包络波函数以及异质结构各带内电子和空穴的分散能量进行了模拟。计算出的吸收峰聚集在光子波长~ 0.76µm处，证实了所设计的异质结构在光子生物传感器和发光闪烁体中的实用性。

Absorption in Al0.20Ga0.80As-GaAs MQWs Heterostructure

This paper presents a brief study of the GaAs/Al0.20 Ga0.80As material system based photo-detector via simulation of the optical absorption, which has been simulated by making the detailed calculations of the envelope wavefunctions associated with valence and conduction band and as well as calculation of the dispersed energies of electrons and holes within the respective bands of the heterostructure. The calculated absorption peak is found to congregate at the photonic wavelength ~ 0.76 µm, which confirm the utility of the designed heterostructure in photonic biosensors and luminescence scintillators.
