Tight-Binding Simulation Of Electronic Structure For CdHgTe Infrared Material

All the objects in nature with temperature above absolute zero are always radiating infrared waves. The wavelength of infrared wave is longer than the visible light's, ranging from 0.75μm to 1000μm, and the infrared wave can not be observed directly. Infrared detector is an equipment that can detect infrared radiation and convert it to measurable signal, achieving detection and tracking. CdHgTe has always been one of important infrared materials, which has a significant role in national security. The band gaps of CdxHg1-xTe (0
