Important material properties can be explained at the level of quantum physics - for example, whether a material conducts electricity or not. Analysing such quantum states has now revealed that there ...

Semiconductor Physics and Flat Band Potential Semiconductors are materials with electrical properties that lie between those of conductors and insulators. In semiconductors, valence electrons occupy ...

A semiconductor ... band. Insulators have a wide band gap that is difficult for electrons to cross without absorbing a great deal of energy, if they can cross it at all. By contrast, conductors ...

Techniques for Band Gap Engineering vary, including doping, the introduction of impurities into a semiconductor to alter its electrical properties; strain engineering, where stress is applied to ...

Energy band structures of metal and insulator, Definition of semiconductor, Electrons and holes, and Effective mass. In this module, we will cover carrier statistics. Topics include Currents in ...

In this module on metal-semiconductor contacts, we will cover the following topics: Device structure, Equilibrium energy band diagram, Electrostatic analysis, Energy band diagram under bias, ...
