Black phosphorus (BP), a novel two-dimensional (2D) layered semiconductor material, has
attracted tremendous attention since 2014 due to its prominent carrier mobility, thickness …

Over the past decade, two-dimensional semiconductors (2DSCs) have aroused wide
interest due to their extraordinary electronic, magnetic, optical, mechanical, and thermal …

Topological phases with insulating bulk and gapless surface or edge modes have attracted
intensive attention because of their fundamental physics implications and potential …

Topological insulators are new states of quantum matter which cannot be adiabatically
connected to conventional insulators and semiconductors. They are characterized by a full …

Based on first-principles phonon and finite temperature molecular dynamics calculations
including spin-orbit coupling, we showed that free-standing single-layer phases of bismuth …

Since graphene has been successfully exfoliated, two-dimensional (2D) materials constitute
a vibrant research field and open vast perspectives in high-performance applications …

The hallmark of a topologically insulating state of matter in two dimensions protected by time-
reversal symmetry is the existence of chiral edge modes propagating along the perimeter of …

Photocatalysis is a quite promising technique to solve increasingly energy shortage and
environmental pollution. Due to the specific electronic and optical properties, recent years …

We propose a tune-free scheme to realize Kramers pairs of Majorana bound states in
recently discovered higher-order topological insulators (HOTIs). We show that, by bringing …

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 …
