本文研究了该化合物的结构、组成和化学组成。和光学性质。Si（001）上的束外延。原子力显微镜（AFM）、透射电子显微镜（TEM）、扫描透射电子显微镜（STEM）、能量色散X射线分析（EDS）等。(EDX)光致发光（PL）光谱和量子点的衰减时间测量表明，存在两种不同尺寸的量子点，在PL光谱中贡献两个不同的发射带。[on Scientists（R）]
The authors present a study of the structure, compn. and optical properties of SiGe quantum dots, grown by gas-source mol. beam epitaxy on Si (001). At. force microscopy (AFM), transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), energy dispersive X-ray anal. (EDX), photoluminescence (PL) spectroscopy and decay time measurements of the quantum dots suggest that there are two distinct sizes of quantum dot, contributing two distinct emission bands in the PL spectra.
