Thermopower of a Kondo Spin-Correlated Quantum Dot
Thermopower of a Kondo Spin-Correlated Quantum Dot
The thermopower of a Kondo-correlated gate-defined quantum dot is studied using a current heating technique. In the presence of spin correlations, the thermopower shows a clear deviation from the semiclassical Mott relation between thermopower and conductivity. The strong thermopower signal indicates a significant asymmetry in the spectral density of states …
