Abstract

We present an investigation of the band structure in the semi-metallic two-dimensional (2D) PtSe2 based on thermoelectric transport phenomena. The gate-tuned electrical conductivity and thermoelectric power were measured by varying the temperature using mechanically exfoliated PtSe2 nanosheets, including naturally doped non-neutral samples. Through the synergy of the gate-tuning effect and shifted zero-gate energy level, the semi-metallic band structure of 2D PtSe2 was confirmed by the transport properties in the band over a wide energy range. The temperature dependence of the transport properties was also investigated to determine the band structure and intrinsic properties.
