Application of Finite Element Simulation Software in Semiconductor Pshysics Teaching
With the continuous updating of educational concepts,the finite element simulation soft-ware,named COMSOL Multiphysics is introduced into the teaching of semiconductor physics to conduct quantitative analysis of relevant physics knowledge.In this paper,the energy band structure and carrier concentration profile of the n-AlGaAs/n-GaAs and p-AlGaAs/n-GaAs heterojunction simulated by COMSOL are discussed in detail.On this basis,the working principle of high electron mobility transistor(HEMT),and the current-voltage characteristic diagram of PN junction are introduced.The teaching practice shows that the introduction of COMSOL into the classroom teaching of semiconductor physics can improve students'learning effect and cultivate their ability of scientific research.
