Study of electronic properties of III-V semiconductors and semiconductor-superlattices

摘要: We have studied different methods for calculating band structures of solids and their density states which can predict the electronic properties accurately. Especially, computational like tight binding approximation pseudo potential method been applied to find semiconductors its superlattices. The project work is divided into two parts. In first part, has used solve computationally by MATLAB, energy Eigen values III-V GaAs AlAs IV semiconductor i.e. Ge get a graphical representation structures. second TB-LMTO program uses superlattices (GaAs/AlAs). A comparison conducting behaviour these materials made finally.
