摘要

可见电致发光(EL)是由火花处理的硅产生的，具有广谱的多峰。高分辨率扫描隧道显微镜显示，表面由许多小颗粒组成，其中很大一部分在2 nm范围内，这是扩大带隙所需的。因此，量子约束效应可以解释EL光谱的蓝移。该器件显示出耐用性，并有望应用于硅晶片之间的光通信。

Quantum confinement: mechanism for visible electroluminescence from spark-processed silicon

Visible electroluminescence, (EL) showing a broad spectrum with several peaks, occurs from spark-processed silicon. High resolution scanning tunneling microscopy shows that the surface is composed of many small particles, with a significant fraction in the range of two nm required for bandgap enlargement. Hence quantum confinement effects can explain the blue shift of the EL spectrum. The devices show durability, and applications for optical communication between Si wafers appear possible.
