CN1178391A 开管汞自封碲镉汞材料热处理装置 失效 - 权利终止

开管汞自封碲镉汞材料热处理装置
Abstract:
一种开管汞自封磅镉汞材料的热处理装置,由样品架、密封罩、退火管、不锈钢密封头、隔膜阀、抽气管组成,巧妙地利用汞源兼作自密封密封罩的工质,形成了一种开管方式又具有闭管功能的退火装置;既具有开管装置的方便又具有闭管装置的优点。本装置适宜对N型磅镉汞分子束外延材料进行热处理,也可对液相外延材料、金属有机化学气相淀积材料及块状碲镉汞材料进行调节各种载流子浓度的热处理。
Abstract(English):

A heat treating apparatus for Te-Cd-Hg material is composed of specimen holder, sealing hood, annealing tube, stainless steel sealing joint, diaphargm valve and air pumping pipe. The Hg source is also used as the self-sealing medium of sealing hood, so forming an annealing apparatus both in open mode and with enclose function. The apparatus is suitable for heat treatment of N-type Te-Cd-Hg molecular beam epitaxy material, liquid epitaxy material, organic chemical metallic gas-phase deposit material and block of Te-Cd-Hg material to regulate the carrier concentration.
