Topological phase transitions have been actively investigated to understand the fundamental properties and to develop applications for spintronics. In this study, we focused on Sb ultrathin films that undergo a topological phase transition by lattice

We have investigated the structure of χ3-borophene on Ag(111), a monolayer material of boron atoms, via total-reflection high-energy positron diffraction (TRHEPD). By comparing the experimental rocking-curves with ones for several structures calcula

The set of known single-atomic-layer (SAL) superconductors has been limited so far by a few examples, including Si(111)-hex- 7 × 3 -In reconstruction, Si(111)-SIC-Pb and -HIC-Pb phases, and Si(111) 3 × 3 -(Tl, Pb) compound phase. In the present stu

We found that a surface state induced by hydrogenation on the surface of $\mathrm{SrTi}{\mathrm{O}}_{3}(001)$ (STO) did not obey the rigid-band model, which was confirmed by in situ electrical resistivity measurements in ultrahigh vacuum. With exposu

The authors investigate quantum phase transitions in single unit-layer NbSe${}_{2}$. The superconductor--normal state transition caused by the surface-normal magnetic field is found to be intermediated by a quasimetallic state. This behavior is consi

We report the direct evidence for superconductivity in Ca-intercalated bilayer graphene C6CaC6, which is regarded as the thinnest limit of Ca-intercalated graphite. We performed the electrical transport measurements with the in situ 4-point-probe met
