SiC薄膜的SSMBE外延生长及其结构表征的开题报告
摘要：
SiC材料具有优异的高温、高功率与高频特性，被广泛应用于微波、功率电子器件、半导体照明、太阳能电池等领域。然而，由于SiC材料本身的内在特性，以及制备过程中的多种因素，使得SiC薄膜的制备技术仍有待提高。
本文将研究使用分子束外延（SSMBE）技术制备SiC薄膜的方法及其结构表征。在外延生长过程中，我们将通过调节温度、气压、流量等参数，控制薄膜的生长速率和质量。同时，使用X射线衍射仪、扫描电子显微镜、拉曼光谱仪等多种手段进行对其结构和性质的表征，评估薄膜品质与适用性。
预期成果为：（1）建立SiC薄膜的SSMBE微晶生长技术；（2）开展面向硅生产的半绝缘和N型SiC外延薄膜生长技术；（3）获得表征薄膜品质和物性的关键技术。

Abstract:
SiC material has excellent high temperature, high power and high frequency characteristics, and is widely used in microwave, power electronic devices, semiconductor lighting, solar cells and other fields. However, due to the intrinsic properties of SiC material and various factors in the preparation process, the preparation technology of SiC film still needs to be improved.
This paper will study the method of preparing SiC film using molecular beam epitaxy (SSMBE) technology and its structure characterization. In the epitaxial growth process, we will control the growth rate and quality of the film by adjusting parameters such as temperature, pressure, and flow rate. At the same time, we will use X-ray diffractometer, scanning electron microscope, Raman spectrometer and other methods to characterize its structure and properties, and evaluate the quality and applicability of the film.
The expected results are: (1) establish the SSMBE microcrystal growth technology of SiC film; (2) develop the growth technology of semi-insulating and N-type SiC epitaxial film for silicon production; (3) obtain key technologies for characterizing the quality and physical properties of films.
Keywords: SiC film; molecular beam epitaxy (SSMBE); growth technology; structure characterization.
