摘要约翰·S.步行者伊利诺伊大学Urbana-Champaign CTS-9419484 计算机电路和光学设备是在从半导体晶体如硅、砷化镓和磷化铟切割而成的晶片上生产的。 计算机和光学器件的进步产生了对更好晶体的需求。 晶体是从一定体积的液体中生长出来的,其性质由晶体生长过程中液体的运动决定。 磁场可以用来控制液体的运动,从而产生具有更好性能的晶体。 数学和数值方法用于预测特定磁场将如何影响液体运动和晶体的性质。 随着模型的开始发展,磁场可以被优化,以实现晶体性能的最大可能的改善。 改进的晶体将导致更快和更可靠的计算机电路和上级光学器件,如激光和高速光通信系统。
英文摘要
ABSTRACT John S. Walker Univ. of ILL. Urbana-Champaign CTS-9419484 Computer circuits and optical devices are produced on wafers sliced from crystals of semiconductors such as silicon, gallium-arsenide and indium-phosphide. Advances in computers and in optical devices have produced a demand for better crystals. A crystal is grown from a volume of liquid, and its properties are determined by the motion of the liquid during crystal growth. A magnetic field can be used to control the liquid motion and thus produce crystals with better properties. Mathematical and numerical methods are used to predict how a specific magnetic field will affect the liquid motion and the properties of the crystal. With the models begin developed, the magnetic field can be optimized in order to achieve the greatest possible improvement in the properties of the crystals. Improved crystals will lead to faster and more reliable computer circuits and to superior optical devices, such as lasers and high-speed optical communication systems.
