Dimensionality-tuned semimetal-to-metal transition in 1T<sub>d</sub>-MoTe<sub>2</sub>

ORAL

Abstract

We study magnetotransport in 1Td-MoTe2 ultrathin flakes at low temperature. The samples are fabricated by mechanical exfoliation and capped with hBN to protect from oxidation. In contrast to bulk crystals, which show large magnetoresistance due to near-perfect electron-hole compensation, we find greater charge imbalance with reduced thickness. The results may explain stabilization of the orthorhombic phase in ultrathin samples as found by He et al.
