This paper reviews recent experimental and theoretical work on some low-index surfaces of
the group V semimetal bismuth. The main focus is on the geometric and electronic structure …

Electron excitations in metal systems play an important role in many chemical and physical
phenomena. They are of paramount importance for energy transfer in photochemical …

Topological insulators are materials with a bulk excitation gap generated by the spin-orbit
interaction that are different from conventional insulators. This distinction is characterized by …

We study the electronic surface states of the semiconducting alloy bismuth antimony (Bi 1− x
Sb x). Using a phenomenological tight-binding model, we show that the Fermi surface for the …

Bismuthene, the last and heaviest group-VA elemental two-dimensional material, has
received tremendous interests owing to its advantages in electronic-transport, semimetallic …

Bismuthene, a mono-elemental two-dimensional material with a novel kind of few-layer
structure purely consisting of bismuth, has been predicted to have a prominent optical …

Employing first-principles calculations, we perform a systematic study of the electronic
properties of thin (one to six bilayers) films of the semimetal bismuth in (111) and (110) …

The electronic structure of non-magnetic low-dimensional materials can acquire a spin
structure due to the breaking of the inversion symmetry at the surface or interface. This so …

We present first-principles calculations of a (3× 3) R 30° Bi∕ Ag (111)-ordered surface alloy,
which has recently been investigated experimentally using angle-resolved photoemission …

In order to explain the anisotropic Rashba-Bychkov effect observed in several metallic-
surface-state systems, we use k· p perturbation theory with a simple group-theoretical …
