Mott variable-range hopping transport in a MoS₂ nanoflake.

ABSTRACT: The transport characteristics of a disordered, multilayered MoS₂ nanoflake in the insulator regime are studied by electrical and magnetotransport measurements. The MoS₂ nanoflake is exfoliated from a bulk MoS₂ crystal and the conductance G and magnetoresistance are measured in a four-probe setup over a wide range of temperatures. At high temperatures, we observe that ln G exhibits a -T ^-1 temperature dependence and the transport in the nanoflake dominantly arises from thermal activation. At low temperatures, where the transport in the nanoflake dominantly takes place via variable-range hopping (VRH) processes, we observe that ln G exhibits a -T ^-1/3 temperature dependence, an evidence for the t
