The meaning of VALENCE BAND is the range of permissible energy values that are the highest energies an electron can have and still be associated with a particular atom of a solid material.
valence band Acronyms Encyclopedia Wikipedia Related to valence band:Fermi level valence band n. The outermost electron shell of atoms in an insulator or semiconductor in which the electrons are too tightly bound to the atom to carry electric current. ...
价带[1](valence band)或称价电带,通常是指半导体或绝缘体中,在0K时能被电子占满的最高能带.对半导体而言,此能带中的能级基本上是连续的.全充满的能带中的电子不能在固体中自由运动.但若该电子受到光照,它可吸收足够能量而跳入下一个容许的最高能区,从而使价带变成部分充填,此时价带中留下的电子可在固体中...

It is found that the offset between the average energies of valence-band maximum is affected little by the elastic strain for the three interface systems, however, those between the topmost valence-band states (ΔE v ) is closely related to the strain condition. The change regions of ΔE v...
High angular resolution and high-energy-resolution x-ray photoelectron spectroscopy (XPS) measurements of the Ir valence bands are presented. Valence-band XPS spectra are reported for Ir(001) as a function of the polar angle in the (100) and (110) mirror planes, with an angular resolution of...
A technique is demonstrated to measure the band alignment between the silicon substrate and the gate electrode using the valence-band electron tunneling (VBET). When ann-channel metal-oxide-semiconductor field-effect transistor is biased in inversion the valence-band electron from the Si substrate ca...
Recent instrumental progress of valence-band photoemission in the X-ray range allows uncovering bulk- and surface-related electronic properties. Four-dimensional recording of energy and momentum-vector gives access to the complete spectral-density functi
