由于量子尺寸受限效应和超周期性的存在,超晶格量子阱的导带中形成了量子化的子能带.这些子能带可以由控制垒宽、垒高和阱宽,以及由设计阱的形状而得到剪裁,使导带中子能带间光跃迁的红外共振吸收峰在相当宽的范围得到调节.所谓量子阱红外探测器,就是利用半导体超晶格量子阱材料子带间光跃迁的红外吸收特性研制而成的一种新颖、快速、高灵敏
Due to quantum size-limited effects and super-periodic existence, the quantized sub-energy bands are formed in the conduction band of the superlattice quantum wells.These sub-energy bands can be controlled by the base width, the base height and the well width, The shape of the well is tailored so that the infrared resonance absorption peak of the light transition between the conduction band neutron energy bands can be adjusted within a relatively wide range .. The so-called quantum well infrared detector is the use of semiconductor superlattice quantum well material sub-band light The infrared absorption characteristics of the transition developed from a new, fast, highly sensitive
