Synthesis of Large-Scale Monolayer 1T'-MoTe₂ and Its Stabilization via Scalable hBN Encapsulation.

ABSTRACT: Out of the different structural phases of molybdenum ditelluride (MoTe₂), the distorted octahedral 1T' possesses great interest for fundamental physics and is a promising candidate for the implementation of innovative devices such as topological transistors. Indeed, 1T'-MoTe₂ is a semimetal with superconductivity, which has been predicted to be a Weyl semimetal and a quantum spin Hall insulator in bulk and monolayer form, respectively. Large instability of monolayer 1T'-MoTe₂ in environmental conditions, however, has made its investigation extremely challenging so far. In this work, we demonstrate homogeneous growth of large single-crystal (up to 500 μm) monolayer 1T'-MoTe₂ via chemical vapor deposition (CVD) and its stabilization in air w
