Martensitic transformation-assisted large thermal conductivity switching in Mn2V2O7 crystals
Materials that can switch between low and high thermal conductivity states enable on-demand management of temperature and heat flow, which will advance the application of solid-state refrigeration, energy conversion, and thermal circuits. Here, we report a large thermal conductivity on/off ratio of ∼1.49, accompanied b...
