摘要

利用截面透射显微镜和[001]区上亮场成像模拟技术，研究了埋藏和未埋藏In/sub x/Ga/sub 1-x/As/GaAs量子点(QDs)的形貌。研究表明，埋地和未埋地的量子点均呈透镜状。

Transmission electron microscopy determination of quantum dot profile

Investigation of the morphology of buried and unburied In/sub x/Ga/sub 1-x/As/GaAs quantum dots (QDs) has been carried out using cross-section transmission microscopy and the [001] on-zone bright-field technique with image simulation. The study shows that both the buried and unburied QDs are lens-shaped.
