Topological Kondo insulators: Negative pressure tuning

Nature Materials, Published online: 27 June 2017; doi:10.1038/nmat4925

Large tensile pressure applied to the putative topological Kondo insulator SmB₆ results in an expansion of the lattice in all directions, and a huge increase in the temperature range over which surface-dominated conduction can be observed.

向假定的拓扑近藤绝缘子SmB ₆施加较大的拉力会导致晶格在所有方向上膨胀，并且在可以观察到表面主导的导电的温度范围内会大大增加。
