中文摘要: 采用水平滑移式液相外延技术制备了不同形貌的InSb量子点,并利用扫描电子显微镜(SEM)、能量色散谱(EDS)和Raman光谱研究了量子点的微观结构及其光学性质.SEM表明制备的InSb量子点易发生团聚,其粒径随着过冷度的增大而增大.EDS谱中出现了量子点的In和Sb元素峰.在182 cm-1波数处,Raman光谱中观察到InSb量子点的横向光学声子(TO)模式.
中文关键词: InSb量子点  液相外延  微观结构
Abstract:InSb quantum dots(QDs) with different morphologies are prepared by horizontally sliding liquid phase epitaxy(LPE) technique. Their microstructures and optical property are investigated by scanning electron microscope(SEM), energy dispersive X-ray spectroscopy(EDS) and Raman spectrum. SEM shows that InSb QDs tend to conglomerate and their particle sizes increase with decrease of the grow temperature. EDS test shows peaks from elements In and Sb appear. The vibration mode from transverse optical(TO) phonons is observed at 182 cm-1 by Raman spectrum.
