| Abstract: | Semiconductor quantum dots have potential applications in many key areas of modem technology. The dimension and composition of quantum dots are very important in determining the opto-electronic properties of the quantum dots. However, the characterization of quantum dot composition profiles is a very challenging task because of small quantum dot sizes. In this papers, we review how energy-filtered transmission electron microscopy is applied to the investigation of quantum dot composition. |
