拓扑半金属ZrSiS表面分子束外延生长银膜OA
Molecular beam epitaxy growth of silver film on topological semimetal ZrSiS
利用分子束外延技术,在拓扑节点线半金属ZrSiS和超导NbSe2 表面成功生长了Ag膜,并重点对ZrSiS表面电子态与量子限域效应进行了研究.实验表明,金属银的引入对费米能下的态密度峰位有显著的调节作用,在 0.4K极低温下未发现Ag/ZrSiS体系的超导迹象,因尺寸效应在ZrSiS表面银岛上产生了周期性的电子态驻波.这些研究结果说明Ag/ZrSiS的异质界面是研究拓扑材料中量子态受限行为的有效平台,为相关拓扑和超导异质结研究提供了实验基础.
Using molecular beam epitropy,Ag films were successfully grown on the surfaces of topological nodal-line semimetal ZrSiS and superconducting NbSe2,with a focus on investigating the electronic states and quantum confinement effects on the ZrSiS surface.The experiments showed that the introduction of silver metal significantly modulated the density of states peaks below the Fermi energy.No signs of superconductivity were observed in the Ag/ZrSiS system at an extremely low temperature of 0.4 K.Due to the size effect,periodic electronic standing waves were generated on the silver islands on the ZrSiS surface.These results indicated that the Ag/ZrSiS heterointerface is an effective platform for studying the confined behavior of quantum states in topological materials,and provided an experimental basis for related research on topological and superconducting heterojunctions.
