PbTe single crystals with five different stoichiometric proportions have been grown using Bridgman method from the starting materials of high pure Te(99.9%)and five times purified Pb, and some of their properties have also been investigated.

• 作者用布里奇曼法以高纯的Te(99.；9%25)和经过5次提纯的Pb合成了5种组分的PbTe单晶；并对它们的物理特性进行了研究。
