The band gap Eg of semiconductors is an important parameter both for the development of infrared detectors and for the studies of band structures. In the latter case, E? is one of the two funda-科学通报:英文版褚君浩徐世秋汤定元
In the case when the lattice period is much smaller that the Debye screening length, the energy diagram has the shape of a sawtooth-like pattern. 展开 关键词: Graded-band-gap semiconductors, Energy diagram, Superlattices, Multilayer structures ...

An 'Energy Band Diagram' is a graphical representation in semiconductor physics that illustrates the allowed and disallowed bands of energy in a crystal lattice. It shows the energy levels of electrons in the valence band and conduction band, determining the conductivity properties of the material. ...

Silicon is defined as a semiconductor with fewer free electrons than a conductor but more than an insulator. This unique characteristic makes silicon widely used in electronics. Silicon has two types of energy bands: the conduction band and the valence b

If the material pair is formed from the same semiconductor but of different type (p and n), then the built-in voltage is roughly equal to the energy gap of the semiconductor. For example, a built-in voltage of 1.1 V could be obtained with silicon and values above 3 V could be...
It should be mentioned that the band gap of p-nc-Si:H (~1.7–2 eV) is simplified to be consistent with that of i-a-Si:H because it has little effect on the simulation result (J–V) if the Ea of the doped layer is small enough50,51,52. Evaluation of holes selectivity The ...
