Large‐Area and High‐Quality 2D Transition Metal Telluride

Large‐area and high‐quality 2D transition metal tellurides are synthesized by the chemical vapor deposition method. The as‐grown WTe2 maintains two different stacking sequences in the bilayer, where the atomic structure of the stacking boundary is revealed by scanning transmission electron microscop...

Zusammenfassung:Large‐area and high‐quality 2D transition metal tellurides are synthesized by the chemical vapor deposition method. The as‐grown WTe2 maintains two different stacking sequences in the bilayer, where the atomic structure of the stacking boundary is revealed by scanning transmission electron microscopy. The low‐temperature transport measurements reveal a novel semimetal‐to‐insulator transition in WTe2 layers and an enhanced superconductivity in few‐layer MoTe2.
