## Description

- description: We focus on the electrical and optical properties of monolayer MoTe2
    (1L-MoTe2) flakes fabricated by gold-mediated exfoliation and show that this technique
    is applicable to the development of 1L-MoTe2 channel FETs. It is found that the
    average area of gold-exfoliated flakes is larger than that of conventional tape
    exfoliation. While the samples without a hBN cap layer are easily oxidized by
    atmospheric exposure for 1 day, increasing in the non-radiative recombination
    centers, the surface oxidation of the 1L-MoTe2 can be suppressed by the deposition
    of the hBN cap layer. For the 1L-MoTe2 channel FETs, the transfer characteristics
    show clear ambipolar behavior and excellent switching properties with an on/off
    ratio of 105 in the n-type regime. We show that the graphite/1L-MoTe2 junctions
    form the Schottky barrier with the energy of 280 meV, which is in good agreement
    with the theoretical value, suggesting the formation of an ideal 2D contact consisting
    of an abrupt interface. The gate voltage at the conductivity minimum point shifts
    to the negative value by decreasing the vacuum level, demonstrating that the electrical
    properties of the gold-exfoliated 1L-MoTe2 strongly depend on the environmental
    conditions.
