This paper reviews the status of experiments bearing on the band structure of semiconductors, with particular reference to germanium and silicon. The situation in n-Ge is especially clear, as both cyclotron resonance and magnetoresistance experiments show that the energy surfaces at the bottom of the...
Theory of the valence band energy level structures of germanium and silicon in an external magnetic field THE PROBLEM OF THE VALENCE BAND STRUCTURE OF GERMANIUM AND SILICON IN THE PRESENCE OF AN EXTERNAL MAGNETIC FIELD IS CONSIDERED FROM A QUANTUM MECHANICAL PO... Evtuhov,Viktor - 《Physical Re...
The valence band is quite similar to germanium. Energy terms linear in k which cannot exist in germanium are estimated and found to be small, though possibly of importance at liquid-helium temperature. An absolute calculation of the fundamental optical absorption is made using the cyclotron ...
During the past three years we have developed greatly improved methods for determining the electronic energy band structure of crystals. In the course of perfecting these methods, we investigated the electronic band structure and related physical propert
The small band gap requires an accurate treatment of conduction and valence band interactions while higher bands are treated by perturbation theory. A highly nonparabolic conduction band is found. The valence band is quite similar to germanium. Energy terms linear in k which cannot exist in ...
It details three formalisms for electronic band structure calculation with examples for bulk silicon and germanium using different expansion functions. In the most common form of TB models, the interaction between different orbitals is allowed only if the atomic sites are nearest neighbors and if the...

Understanding how to optimize electronic band structures for thermoelectrics is a topic of long-standing interest in the community. Prior models have been limited to simplified bands and/or scattering models. In this study, we apply more rigorous scattering treatments to more realistic model band stru...

The electronic band structure (or simply band structure) of a given crystal is unique, as is the electronic structure of an atom. The band structure is obtained in the framework of the band theory, which is only an approximation to the quantum state of a solid, and applies to solids consi...
