举例来说,一个p-n接面(p-n junction)的能带会弯折,起因是原本p型半导体和n型半导体的费米能阶位置各不相同,但是形成p-n接面后其费米能阶必须保持在同样的高度,造成无论是p型或是n型半导体的传导带或价带都会被弯曲以配合接面处的能带差异。 上述的效应可以用能带图(band diagram)来解释,。在能带图里...

Energy Diagram of N-type Semiconductor Theenergy banddiagram of this semiconductor is shown below. The free electrons are existing in the conduction band due to adding the Pentavalent material. In the covalent bonds of the crystal, these electrons did not fit. But, a small number of electrons ...
Instead, the nanotube will now be more likely to ‘give up’ its electrons to the p-type side of the heterojunction leaving behind an electron vacancy (hole) in the nanotube that is stabilised by the excess of negative charge carriers provided by the dopant. The main issue with n-type ...
Zewen Xiao1,2, Yoshitake Toda2,3, Hidenori Hiramatsu1,2, Hideo Hosono1,2,3 & Toshio Kamiya1,2 Tin monosulfide (SnS) is a naturally p-type semiconductor with a layered crystal structure, but no reliable n-type SnS has been obtained by conventional aliovalent ion substitution. In...

By the same token, the growth interface of our thick (400 nm) type B film also demonstrated an n-type band diagram. Neglecting the small change in the valence band offset after the transfer of the WS2 film onto the GaN substrate, as the interface attraction was dominated by weak vdW ...
