A Self-Stabilizing Crystal Pulling Process

提出研究一种新的拉晶工艺， 其在制造新型光学器件中的应用 材料和先进电子材料。直拉 拉晶是最广泛使用的工艺， 生产光学和电子的大块单晶 材料.所提出的过程可以潜在地改进 Czochralski工艺是自稳定的， 基本上在稳定状态下运行， 更均匀的直径和掺杂剂浓度的晶体。 拟议的工作将包括计算机模拟流体 流动，传热和传质，以及单个 非线性光学有机材料的晶体和 先进电子材料InP。

It is proposed to study a novel crystal pulling process and its application to the manufacturing of a novel optical material and an advanced electronic material. Czochralski crystal pulling have been the most widely used process for producing bulk single crystals of optical and electronic materials. The proposed process can potentially improve upon the Czochralski process in that it is self-stabilizing and operates essentially in steady state, producing single crystals of more uniform diameter and dopant concentration. The proposed work will include computer simulations of fluid flow, heat and mass transfer, and the growth of single crystals of a non-linear optical organic materials and an advanced electronic material, InP.
