| 1 | ZnO薄膜非线性光学特性的实验研究显示文摘利用金属有机化学气相沉积(MOCVD)技术在蓝宝石衬底上生长一层高质量的ZnO薄膜。为了考察沉积温度对样品的非线性特性的影响,在200~500℃生长了一系列ZnO薄膜。用X射线衍射谱(XRD)及扫描电镜(SEM)对样品结构进行了评价。以Nd:YAG激光器输出的1.06μm的激光为基频光,对ZnO薄膜样品的二阶及三阶非线性光学特性进行了实验研究。实验发现,对于250℃沉积温度的样品有较强的非线性效应,实验测得的二阶非线性极化张量χ(2)ZZZ=9.2pm/V,三阶有效非线性系数χ(3)=5.28×10-20m2/V2。 | 刘成有 宁丹 B.P.Zhang Y.Segawa | 2005 | 光学精密工程2005，13，3： | 11 |
| 2 | III-Nitride-Based Quantum Dots and Their Optoelectronic Applications显示文摘During the last two decades, III-nitride-based quantum dots(QDs) have attracted great attentions for optoelectronic applications due to their unique electronic properties. In this paper, we first present an overview on the techniques of fabrication for III-nitride-based QDs. Then various optoelectronic devices such as QD lasers, QD light-emitting diodes(LEDs), QD infrared photodetectors(QDIPs) and QD intermediate band(QDIB) solar cells(SCs) are discussed. Finally, we focus on the future research directions and how the challenges can be overcome. | G.E.Weng A.K.Ling X.Q.Lv J.Y.Zhang B.P.Zhang | 2011 | Nano-Micro Letters2011，3，3： | 0 |
