The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

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

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 …

Two-dimensional topological insulators with a large bulk band gap are promising for
experimental studies of quantum spin Hall effect and for spintronic device applications …

The introduction of the concept of topology into condensed matter physics has greatly
deepened our fundamental understanding of transport properties of electrons as well as all …

We have grown nearly freestanding single-layer 1 T′-WT e 2 on graphitized 6 H-SiC (0001)
by using molecular beam epitaxy (MBE), and characterized its electronic structure with …

The growing diversity of topological classes leads to ambiguity between classes that share
similar boundary phenomenology. This is the status of bulk bismuth. Recent studies have …

A distinct electronic structure was observed in the single-layer FeSe which shows
surprisingly high-temperature superconductivity over 65 K. Here, we demonstrate that the …

Atomically thin topological materials are attracting growing attention for their potential to
radically transform classical and quantum electronic device concepts. Among them is the …

The two-dimensional topological insulators host a full gap in the bulk band, induced by spin–
orbit coupling (SOC) effect, together with the topologically protected gapless edge states …
