Since the discovery of graphene, 2D materials have attracted significant attention for their
unique properties. Monoelemental 2D materials (ME2DMs) are of particular interest …

Weyl semimetals are a new member of the topological materials family, featuring a pair of
singly degenerate Weyl cones with linear dispersion around the nodes in the bulk, and …

Our sense of time is far from constant. For instance, time flies when we are having fun, and it
slows to a trickle when we are bored. Midbrain dopamine neurons have been implicated in …

Abstract 2D SnTe films with a thickness of as little as 2 atomic layers (ALs) have recently
been shown to be ferroelectric with in‐plane polarization. Remarkably, they exhibit transition …

Topological crystalline insulators are materials in which the crystalline symmetry leads to
topologically protected surface states with a chiral spin texture, rendering them potential …

The unique crystalline protection of the surface states in topological crystalline insulators
has led to a series of predictions of strain-generated phenomena, from the appearance of …

We combine quasiparticle interference simulation (theory) and atomic resolution scanning
tunneling spectromicroscopy (experiment) to visualize the interference patterns on a type-II …

SnTe hosts ferroelectricity that competes with its weak nontrivial band topology: in the high-
symmetry rocksalt structure—in which its intrinsic electric dipole is quenched—this material …

Weyl semimetals constitute a newly discovered class of three-dimensional topological
materials with linear touchings of valence and conduction bands in the bulk. The most …

Topological quantum materials have emerged as promising electrocatalysts for hydrogen
evolution reaction (HER). However, most of their performance is behind noble metals such …
