2.3 Carrie Diffusion
2.4 Carrier Injection
In the preceding section we considered the drift current,that is the transport of carrier when an electric field is applied.Another important current component can exist if there is a spatial variation of carrier concentration in the semiconductor material,that is,the carrier tend to move from a region of high concentration to a region of low concentration.This current component is called diffusion current.前面部分我们提到了漂移电流，就是外加电场下载流子的 ...
