ii型能带排列(type-ii band alignment)的半导体异质结 半导体异质结是由两个不同材料的半导体构成的结构,其中每个材料的能带结构不同。能带排列是指异质结中能带边缘的对齐方式。在ii型能带排列中,导带的最低能级和价带的最高能级分别位于两个半导体中,这意味着电子和空穴在异质结中分别是在不同的半导体中迁移。
ii型能带排列(type-ii band alignment)的半导体异质结 1. 引言 1.1 概述 在当前半导体领域的研究中,半导体异质结作为一种重要的结构形式,被广泛应用于光电子器件、太阳能电池、传感器等领域。其中,ii型能带排列的半导体异质结因其特殊的能带布局而备受关注。本文将重点讨论ii型能带排列在半导体异质结中的性质和应用。
This peculiar momentum space behavior is originated from the relative strength of two distinct mechanisms contributing to the second‐order nonlinear optical (NLO) response, that is, a purely interband transition part and a mixed interband‐intraband contribution. Thus, this study propo...
是能带台阶的一种，半导体和半导体或金属接触的时候会出现能带台阶，包括导带台阶和价带台阶，然后根据台阶...
从能带结构分的，成阶梯状的是2，另一种就是1，可以google一下，有综述
Application of numerical exciton-wave-function calculations to the question of band alignment in Si/Si1-xGex quantum wells We numerically calculate the two-particle ground-state wave functions for excitons in SiGequantum wells in an effective mass model and demonstrate how osci... C Penn,F. Schf...

However, it is challenging to realize the flexible switch of band alignments in heterostructure for diverse applications. In this paper, we systematically investigate the electronic and optical properties of novel heterostructure system composed of emerging two-dimensional material Pd2Se3 and all-inorganic...
In present work using T2SL InAs/AlSb/GaSb based material, we combined these two schemes together and used a BECX as the window layer and engineered the band−alignment of this hetero−face to efficiently extract photo−generated carriers. The new BECX design allows the T2SL–based Vis/e...
