A heterojunction between crystalline silicon and colloidal quantum dots (CQDs) is realized. A special interface modification is developed to overcome an inherent energetic band mismatch between the two semiconductors, and realize the efficient collection of infrared photocarriers generated in the CQD film. This junction is used to produce a sensitive near infrared photodetector.
实现了晶体硅和胶体量子点（CQDs）之间的异质结。开发了一种特殊的界面修饰方法，以克服两种半导体之间固有的能带不匹配，并实现对 CQD 薄膜中产生的红外光生载流子的有效收集。该结用于制作高灵敏度近红外光电探测器。
