Electronic and Optical Properties of Semiconductors

Más información sobre el libro

The study delves into the electronic and optical properties of intrinsic semiconductors through the orthogonal empirical tight binding model. It analyzes bulk properties of semiconductors with zincblende, diamond, and rocksalt structures, extending previous work to higher-order interaction integrals. New parameter sets for specific semiconductors are introduced, improving alignment with experimental data across the Brillouin zone. Additionally, the Hamiltonian of heterostructures is constructed layer by layer using parameters from the bulk constituents.
