2024年10月1日 · In this study, an extraordinary photoluminescence (PL) phenomenon is discovered that originates from a vertical transition between specific bands in the X-point energy valley of K-space in multilayer Weyl semi-metal monoclinic (1T') MoTe2 without a gap structure.
MoTe2 Polymorphs: A DFT Approach to Structural, Electronic, …
Bulk 1T'-MoTe2 crystals exhibit a max. carrier mobility of 4,000 cm2 V-1 s-1 and a giant magnetoresistance of 16,000% in a magnetic field of 14 T at 1.8 K. In the few-layered form, 1T'-MoTe2 exhibits a bandgap opening of up to 60 meV, which our d. functional theory calcns. identify as arising from strong interband spin-orbit coupling.
