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.

伊利诺斯州约翰·s·沃克大学。计算机电路和光学器件是在硅、砷化镓和磷化铟等半导体晶体切片上生产的。计算机和光学设备的进步产生了对更好的晶体的需求。晶体是从一定体积的液体中生长出来的，它的性质是由晶体生长过程中液体的运动决定的。磁场可以用来控制液体运动，从而产生性能更好的晶体。使用数学和数值方法来预测特定磁场如何影响液体运动和晶体的性质。随着模型的建立，可以对磁场进行优化，以最大限度地提高晶体的性能。改进后的晶体将导致更快、更可靠的计算机电路和更先进的光学设备，如激光器和高速光通信系统。
