载流子扩散 meaning in Chinese

carrier diffusion

With the finite - difference method , self - consistent solutions for the possion ' s equation , injected current density , carrier concentration , optical field and thermal conduction equations have been realized to study the thermal - field properties , the coupling of electricity , thermal and optical - fields , and the influences of n - dbr and double oxide - confining regions on the characteristics of vcsels
本文建立了一个直接耦合的准三维理论模型，通过有限差分法求解泊松方程、载流子扩散方程、热传导方程和光场方程的自洽解，研究了vcsel的热场分布特性，并实现了电、热和光场的耦合，同时考虑了n - dbr及双氧化限制层对vcsel特性的影响。
