Chemical Vapor Deposition Growth of Single Crystalline CoTe2 Nanosheets with Tunable Thickness and Electronic Properties

Abstract: Two-dimensional (2D) metallic transition metal dichalcogenides (MTMDs) have recently drawn increasing interest for fundamental studies and potential applications in catalysis, charge density wave (CDW), interconnections, spintorque devices, as well superconductors. Despite some initial efforts, the thickness-tunable synthesis of atomically thin MTMDs remains a considerable challenge. Here we report controlled synthesis of 2D cobalt telluride (CoTe 2 ) nanosheets with tunable thickness using an atmospheric pres… Show more

“…The high‐resolution TEM (HRTEM) image of h ‐CoTe 2 /MXene reveals that the atoms are arrayed in a typical hexagonal ring with a lattice fringe spacing of 0.327 nm, indexed to the (100) plane of h ‐CoTe 2 phase (Figure 1f). [ 39 ] On the contrary, the o ‐P‐CoTe 2 /MXene reveals that the atoms are arranged in an orthorhombic structure with a lattice spacing of 0.282 nm, corresponding to the (111) facet of o ‐CoTe 2 phase (Figure 1g), [ 40 ] which reveals the phase transformation from hexagonal to orthorhombic phase occurrence induced by the P doping. It is worth noting that the dashed yellow circles clearly show the enriched atomic vacancies and defects in o ‐P‐CoTe 2 /MXene.…”
