| 摘 要： | 采用电子回旋共振-等离子体增强金属有机物化学气相沉积（ECR-PEMOCVD）技术，在康宁7101型普通玻璃衬底上沉积了高度c轴择优取向的多晶GaN薄膜. 利用反射高能电子衍射（RHEED) , X射线衍射 (XRD) 对样品进行检测，研究了在低温（430℃）沉积中氮气流量对GaN薄膜结晶性的影响. 并且利用原子力显微镜 (AFM) 和室温光致发光 (PL) 谱研究了薄膜的表面形貌和发光特性，发现薄膜表面形貌较为平整，其发光峰由较强的紫外近带边发光峰和极其微弱的绿光发光峰组成.

| Abstract: | High c-axis oriented GaN films have been deposited on corning 7101 glass substrate by electron cyclotron resonance plasma enhanced metal organic chemical vapor deposition (ECR-PEMOCVD) at low temperature.Influences of N2 flow rate on the crystalline characteristics of the GaN films were investigated by reflection high energy electron diffraction (RHEED) in situ and X-ray diffraction (XRD).And the surface morphology and the optical properties of the GaN film were studied using atomic force microscope (AFM) and room temperature photoluminescence (PL) spectra.The results show that the surface morphology of the GaN film is smooth and its optical peaks are composed of a stronger ultraviolet near band emission and a rather weak green emission. |
