Thermoelectricity of superconducting twisted WSe2 bilayers

Thermoelectric measurements are powerful tools to probe electronic entropy in correlated systems, which is otherwise difficult to access by conventional transport measurements. In this talk, I will present recent progress in thermoelectric measurements in twisted WSe2 bilayers – an emerging platform that simulates high-Tc superconductivity. Our measurements show signs of quantum criticality near correlated insulator state and abnormal Seebeck coefficient enhancement at metallic state at filling ν = 1. This will help to understand the nature of unconventional superconductivity in twisted WSe2 bilayers.
