Abstract The formation of the topological surface state originates from bulk band inversion at the top of the valence band and the bottom of the conduction band. The transition between normal and topological insulators is known as a topological phase

The formation of germanene on Ag(111) has been extensively studied and confirmed. However, the nature of the transition stage between the initial Ag_{2}Ge alloy phase at 1/3 monolayer (ML) and the final quasifreestanding phase germanene phase at cove

The effect of Rashba spin orbit coupling (SOC) on superconductivity remains elusive. Here, the authors report largely enhanced in-plane upper critical magnetic field due to Rashba SOC induced dynamic spin-momentum locking on the surfaces of an atomic

We present an enhanced method for synthesizing sheets of borophane. Despite the challenges associated with low efficiency, we discovered that incorporating hydrochloric acid into the ion-exchange reaction significantly improved the production yield f

Spin–orbit coupling produces spin–orbital-entanglement in quasiparticle eigenstates. Here, Yajiet al. present a general description of spin–orbital-entangled states and establish a model for dipole transition based on spin-dependent quantum int

We experimentally prepared a ferromagnet with an L10-FeCo ordered structure by inserting a periodic buffer layer to suppress the B2 structural transition and to maintain the L10 structure. The sample was fabricated by utilizing a technique involving

By measuring the spin polarization of GeTe films as a function of light polarization we observed that the bulk states are fully spin polarized in the initial state, in strong contrast with observations for other systems with a strong spin-orbit inter

We propose a table-top method to obtain bilayer quasi-free-standing epitaxial-graphene (QFSEG) on SiC(0001). By applying a microwave annealing in air to a monolayer epitaxial graphene (EG) grown on SiC(0001), the buffer layer is decoupled from the Si

The creation of three-dimensional (3D) geometrical shapes with atomically ordered surfaces and the investigation of their physical properties are major steps contributing to the development of a new paradigm in surface science. We produced a 3D-patte
