Sb2Se3 是一种高度各向异性的半导体，因此其平面和衍射图案的明确米勒索引非常重要 - 为基础研究准备单晶的定向和索引表面也很重要。这封信的目的有两个：a) 引起人们对 Sb2Se3 流行使用的两种不同的米勒索引约定的关注（空间群编号 62，设置 Pnma 和 Pbnm），解释它们与其晶体结构的关系并为报告协议提出建议；b) 引起人们对制备用于物理研究的 Sb2Se3 单晶的三个 {100} 型面的非 X 射线方法的关注。
Sb2Se3 is a highly anisotropic semiconductor and unambiguous Miller indexing of its planes and diffraction patterns is therefore important - as is the preparation of oriented and indexed surfaces of single crystals for fundamental studies. The purpose of this letter is twofold: a) to bring attention to the two different Miller indexing conventions in popular use for Sb2Se3, (Space group Number 62, settings Pnma and Pbnm) explaining how they are related to its crystal structure and making recommendations for reporting protocols, and b) to draw attention to a non-x-ray method of preparing the three {100} type faces of single crystals of Sb2Se3 for use in physical investigations.
