Thermoelectric power of overdoped Tl2201 crystals: charge density waves and resistivities
We report measurements of the in-plane thermoelectric power (TEP) for an overdoped (OD) crystal of the single layer cuprate superconductor Tl2Ba2CuO6+x (Tl2201) at several hole concentrations (p), from 300 or 400 K to below the superconducting transition t ...
Bristol2024Electrically tunable giant Nernst effect in two-dimensional van der Waals heterostructures
Andras Kis, Guilherme Migliato Marega, Zhe Sun, Gabriele Pasquale
The Nernst effect, a transverse thermoelectric phenomenon, has attracted significant attention for its potential in energy conversion, thermoelectrics and spintronics. However, achieving high performance and versatility at low temperatures remains elusive. ...
2024Magneto-Thermoelectric Transport in Graphene Quantum Dot with Strong Correlations
Disorder at etched edges of graphene quantum dots (GQD) enables random all-to-all interactions between localized charges in partially filled Landau levels, providing a potential platform to realize the Sachdev-Ye-Kitaev (SYK) model. We use quantum Hall edg ...
