On the basis of our results we provide some practical rules to tune the valence band maximum, conduction band minimum, and band gap in this class of materials.doi:10.48550/arXiv.1412.3659Simone MeloniGiulia PalermoNegar Ashari AstaniBasile F. E. Curchod...
aSemiconductor photocatalyst is composed of low valence band filled with electronic and high empty conduction band, the band is the band gap is formed between the valence band and the conduction band. 半导体photocatalyst由低化学价带组成充满电子,并且高空的传导带,带是带隙被形成在化学价带和传导带之间...
The chapter Band theory covers many important concepts, one of them is about the forbidden energy gap. It is defined as the gap between the valence band and conduct band. The gap between the valence band and conduction band. If this gap is greater then it means valence band electrons are ...
Meanwhile, the type-II heterojunctions are formed because the conduction band minimums andvalence bandmaximums are respectively contributed by WS2 (or WSe2) and GaN. 同时, 由于导带底和价带顶分别由WS2(或WSe2) 和GaN贡献, 这两种复合结构形成了第二类异质结. ...

aIn semiconductor physics, the band gap of a semiconductor is always one of two types, a direct band gap or an indirect band gap. The band gap is called "direct" if the momentum of electrons and holes is the same in both the conduction band and the valence band; an electron can direct...
The conduction-band and valence-band effective-mass parameters have been calculated for 11 zinc-blende semiconductors. The k路p method is used to calculate these effective masses in the vicinity of k=0. The matrix elements of px are foun... Richard,L.,Bowers,... - 《Physical Review B》 ...
