Contribution of Berry Curvature to Thermoelectric Effects
Contribution of Berry Curvature to Thermoelectric Effects
Within the semiclassical Boltzmann transport theory, the formula for Seebeck coefficient S is derived for an isotropic two-dimensional electron gas (2DEG) system that exhibits anomalous Hall effect (AHE) and anomalous Nernst effect (ANE) originating from Berry curvature on their bands.Deviation of S from the value S 0 estimated neglecting Berry …
