Nanometer semiconductor quantum dots have potential application in the novel quantum functional devices because of their unique photoelectric and transport properties. Recently, as a main fabricatting method of nanoquantum dots, self assembling growth has received wide attention. In order to further improve the performance of these devices, the formation of ordered nanoquantum dots is a key factor. In the paper, we briefly review new development of the study on self assembling growth.
