量子阱

Quantum Well

A semiconductor structure formed by sandwiching a thin layer of a lower-bandgap material between two layers of a higher-bandgap material, which confines charge carriers (electrons and holes) in one dimension, leading to quantized energy levels. / 一种半导体结构，由夹在两层宽带隙材料之间的薄层低带隙材料形成，在垂直方向上限制载流子，导致能级量子化。
