Abstract
The quantum pitfall component is refers to the photoelectron component uses quantum pitfall material achievement to have the source area , the material grows is generally uses the MOCVDextension technology. Quantum pitfall has the structure like sandwich ,middle is a very thin semiconductor membrane,and the flank is two insulating layers.Shines with the laser toward the quantum pitfall,can cause the semiconductor level in the middle to produce electronic and th belt positive electricity hole. This article are main introduction compound semiconductor quantum pitfall component's historical development and some common applications, in also emphatically introduced the quantum pitfall component in the laser, light switch, light modulator aspect's application, and described it in various aspects development condition and the prospect.
