The fabrication, by droplet epitaxy, of a class of quantum nanostructures characterized by a regular, nanometres high, flat disks with a diameter of hundreds of nanometres and a hole at the centre encircled by a ring a few nanometres high, is presented here. A detailed analysis of the growth kinetics performed via in situ and ex situ probes allows us to propose a working model for the formation of these structures.
本文介绍了通过液滴外延法制造一类具有规则的、纳米高的扁平盘的量子纳米结构，这些盘的直径为数百纳米，中心有一个孔，孔周围有一个几纳米高的环。通过原位和非原位探针进行的生长动力学详细分析，使我们能够提出这些结构形成的工作模型。
