Bismuthene, an emerging two-dimensional monoelemental material as a good candidate of
the room-temperature topological insulator, has attracted considerable attention due to its …

Heterostructures of two-dimensional layered materials can be functionalized with exotic
phenomena that are unpresented with each constituting component. The interface effect …

The presence of inherently strong spin–orbit coupling in bismuth, its unique layer-dependent
band topology and high carrier mobility make it an interesting system for both fundamental …

The recent application of topological quantum chemistry to rhombohedral bismuth
established the nontrivial band structure of this material. This is a second-order topological …

Topological superconductivity is one of the frontier research directions in condensed matter
physics. One of the unique elementary excitations in topological superconducting state is the …

Topological materials are typically characterized by gapless boundary states originated from
nontrivial bulk band topology, known as topological bulk-boundary correspondence …

The discovery of quantum spin Hall materials with huge bulk gaps in experiment, such as
bismuthene, provides a versatile platform for topological devices. We propose a topological …

We present a detailed study of the growth of Bi films on superconducting Nb (110) substrates
in dependence on the Bi coverages and the Nb surface quality. We find that Bi grows in a …
