针对非均匀寿命分布情况,建立了描述电导调制基区的双极输运方程,并利用Liouville_Green变换获得该方程在不同边界条件下的WKB解.其结果可用于局域寿命控制下电导调制器件的建模分析.
According to the distribution of non-uniform lifetime, a bipolar transport equation describing the conductance modulated base region is established and the WKB solution of this equation under different boundary conditions is obtained by Liouville_Green transform. The results can be used for the local lifetime control of the conductivity modulation device Modeling analysis.
