Abstract

The structure of the layered Sr_xBi₂Se₃ crystals characterized by the nematic superconductivity has been studied. It is shown that the higher the degree of the superconducting and structural nematicity, the stronger the deviation of the block boundary orientation from the crystal c axis. This indicates that the block grows at an angle to the basal planes, rather than along them. This growth can result in the formation of the preferred direction in a system.

邻里生长是Sr x Bi 2 Se 3中向列超导的可能结构来源

摘要

研究了以向列超导为特征的层状Sr _x Bi ₂ Se ₃晶体的结构。结果表明，超导程度和结构向列性越高，嵌段边界取向与晶体c轴的偏差越大。这表明块体与底面成一定角度而不是沿着底面生长。这种增长可以导致系统中首选方向的形成。
