Two-dimensional tellurides are promising for 2D topological insulators and type-II Weyl semimetals. In article 1603471, J. Lin, G. Liu, Z. Liu, and co-workers report the large-scale growth of large-size and high-quality atomically layered MoTe2 and WTe2, using a chemical vapor deposition (CVD) method. STEM imaging identifies the atomic structures of WTe2 and MoTe2. Electric-transport measurements reveal the semimetal-to-insulator transition in WTe2 and superconductivity in MoTe2.
