Investigation on the phase-transition-induced hysteresis in the thermal transport along the c-axis of MoTe2

Thermal conductivity: in a loop The thermal conductivity across stacked MoTe2 layers exhibits a hysteresis loop, as the temperature changes. Similar effects in other materials have been exploited for the implementation of thermal memories for the storage of phononic information. Now, a team from Nan...
