ABSTRACT -- CTS-9311893 Williams The application of a transverse magnetic field to Czochralski crystal growth of semiconductors has been found to improve the distribution of dopants and the crystal quality itself. However, optimal results are impossible to obtain without an understanding of the melt flow, which has proved elusive. The PI proposes to formulate the initial development of a three-dimensional spectral method numerical model to examine the melt growth for moderate to high magnetic field strengths. The planning activities will consist of an in-depth literature review, and a close examination of the governing equations, boundary conditions, and simplifications. Care will be taken to fully explore the aims and motivations of the larger numerical study, and to initiate and maintain contact with experimentalist in the field. Initial numerical studies will be performed to promote familiarity with the computational and graphical techniques.

研究发现，在半导体中应用横向磁场可以改善掺杂剂的分布和晶体本身的质量。然而，如果不了解熔体流动，就不可能获得最佳结果，这已被证明是难以捉摸的。PI建议制定一个三维光谱方法数值模型的初步发展，以研究中高磁场强度下熔体的生长。规划活动将包括深入的文献审查，以及对控制方程、边界条件和简化的仔细检查。本课程将充分探讨大型数值研究的目的和动机，并与该领域的实验人员建立和保持联系。初步的数值研究将进行，以促进熟悉的计算和图形技术。
