Recently, the research team of Mathieu Gemet of the University of Grenoble Alpes in France clearly observed the Guernest effect in a single layer of tungsten diselenide through an ingenious experiment, confirming the Su Gang study of the University of Chinese Academy of Sciences The theoretical prediction given by the team in 2015, the experimental results are in good agreement with the theoretical predictions, and have great development potential in the future large-scale application of thermoelectric conversion devices. Related research was published in "Nature-Communication". In 2015, Su Gang, a professor at the University of Chinese Academy of Sciences, and other researchers explored the spin Nernst effect in single-layer transition metal chalcogenides and proposed a new effect, the Guernst effect. This effect describes that the carriers of the K-energy valley and the -K-energy valley are driven by a longitudinal temperature gradient. Due to their different chirality, under the effect of the Bailey curvature, they will move in a direction perpendicular to the temperature gradient Deflect, thereby generating a lateral energy valley. Researchers such as Mathieu Jemet used epitaxial growth to prepare high-quality single-layer and multi-layer tungsten diselenide on graphene-silicon carbide liners. In order to remove the degeneracy of the energy valley, a nickel-iron alloy layer was introduced, and the single spin was pumped into the tungsten diselenide layer through the ferromagnetic resonance spin pump technology, and the difference between the K and -K energy valley particles was established. Balanced distribution, which in turn produces an observable voltage in the lateral direction. The results of their measurement experiments are not only in good agreement with the theoretical predictions given by Su Gang's team, but also because of the huge Nernst coefficient, this has great potential for development in the actual large-scale application of thermoelectric conversion devices.
