摘要
移动加热器法被认为是一种切实可行的生长大尺寸、高质量单晶体的方法,它结合了液相外延和区熔提纯的优点.本文阐述了移动加热器法晶体生长的基本原理、优缺点,综述了相关加热方式、晶体生长过程中的质量输运和热交换,并探讨了工艺条件(如重力场、磁场、强迫对流等和晶体生长速率)对移动加热器法生长晶体过程与晶体质量的影响,最后对移动加热器法的发展趋势进行了展望.
Travelling heater method is known as the most effectiveviable technique to grow single crystals with large size and high quality single crystals.It combines the advantages of both liquid phase epitaxy and zone melting purification techniques.This article reviews Tthe fundamentalsbasic principles,advantages and disadvantages of crystal growth techniquecs with travelling heater were reviewed.The heating method,as well as the mass and heat transport duringin the process of crystal growth has been also,was described.The effectinfluences of the processing parameters,including gravitational field,magnetic field and forced convection together withas well as growth rate,on the crystal growth processdure and the crystal ingot quality has beenwere discussed.Finally And the development trend of this technics iswas prospected.
