Distinct from most semiconducting transition-metal sulfide and selenide compounds that are
only stable in the 2H phase, tellurides exhibit much richer structural variations and electronic …

Nonsymmorphic space group symmetries can generate exotic band crossings in topological
metals and semimetals. Here, based on symmetry analysis and first-principles calculations …

The pronounced quantum confinement effects, outstanding mechanical strength, strong light–
matter interactions and reasonably high electric transport properties under atomically thin …

Topological insulators hold great promise for dissipationless transport devices due to the
robust gapless states inside the insulating bulk gap. So far, several generations of …

Progress on researches of two-dimensional (2D) metals strongly relies on development of
the growth technique. Studies on preparation of 2D metals have so far been limited, and this …

The electron-phonon coupling (EPC) in a material is at the frontier of the fundamental
research, underlying many quantum behaviors. van der Waals heterostructures (vdWHs) …

Platinum telluride (PtTe2), a member of metallic noble-transition-metal dichalcogenides
(MNTMDs), has emerged as an indispensable candidate for superconducting, magnetic …

We investigate the optical response induced by a dc current flowing in a nonmagnetic
material that lacks inversion symmetry. In this class of materials, the flowing current …

Abstract Recently, two-dimensional (2D) ternary layered telluride materials have attracted
enormous attention due to their exotic electronic properties. Here, we propose two new …

One or a few layers of van der Waals (vdW) materials are promising for applications in
nanoscale electronics. Established properties include high mobility in graphene, a large …
