The structures and properties of Si/SiO2 core/shell quantum dots studied by density-functional tight-binding calculations

Huilong Dong, Tingjun Hou, and Xiaotian Sun et al.

Si/SiO2 core/shell quantum dots (QDs) have been shown with wavelength-tunable photoluminescence in addition to their inert, nontoxic, abundant, low-cost, biocompatible advantages. Due to their big size, here, we apply density-functional tight-binding (DFTB) method to perform calculations to study ... [Appl. Phys. Lett. 103, 123115 (2013)] published Fri Sep 20, 2013.
