Abstract

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 .

Keywords: 2D materials; MoTe2; WTe2; chemical vapor deposition.
