Tunneling spectroscopic signatures of charge doping and associated Mott transition in $\alpha$-RuCl${}_3$ in proximity to graphite

Xiaohu Zheng, Ke Jia, Junhai Ren +5

The layered Mott insulator $\alpha$-RuCl${}_3$ has been extensively studied as a potential Kitaev quantum spin liquid candidate. Here, by constructing heterostructures with graphite, we…
