キーワードThermoelectricity / DFT calculation / 2D materials / Photocatalytic / Optical properties / 3D semimetals / Raman spectra
研究実績の概要

In this fiscal year, six papers and one textbook were published, which are summarized as follows:
(1) We found an unusual thermoelectric behavior in 3D Dirac and Weyl semimetals, called the Hall thermoelectric effect. We also found that the van Hove singularities of the 3D nodal-line semimetal can enhance thermoelectric performance.
(2) We designed a new 2D Janus material, Ge2SSe, which can synthesize and show high performance for thermoelectric and photocatalytic.
(3) We published a book introducing first-principles calculations using the Quantum ESPRESSO package, a powerful tool for multidisciplinary research.
(4) We collaborated with the experimental groups to study the optic and Raman spectra of 2D and 1D materials, such as graphene, MoTe2, W6Te, etc.
