A Self-Stabilizing Crystal Pulling Process

提出了一种新的晶体拉拔工艺及其在新型光学材料和先进电子材料制造中的应用。提拉法是目前应用最广泛的光学和电子材料块体单晶制备工艺。拟议的工艺可能会改进提拉法，因为它是自稳定的，基本上是在稳定状态下操作，产生直径更均匀、掺杂浓度更均匀的单晶。拟议的工作将包括流体流动、传热和传质的计算机模拟，以及非线性光学有机材料和先进电子材料InP的单晶生长。

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.
