Strong Crystalline Thermal Insulation Induced by Extended Antibonding States
Ruihuan Cheng, Chen Wang, Niuchang Ouyang +2
Crystalline solids with extreme insulation often exhibit a plateau or even an upward-sloping tail in thermal conductivity above room temperature. Herein, we synthesized a crystalli…
