Abstract
Large-area and high-quality 2D transition metal tellurides are synthesized by the chemical vapor deposition method. The as-grown WTe<sub>2</sub> 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 WTe<sub>2</sub> layers and an enhanced superconductivity in few-layer MoTe<sub>2</sub> .
