Beyond surfaces: quantifying internal radiative heat transport in dense materials
Janak Tiwari, Tianli Feng
While phonons and electrons are well-established heat carriers in solids, photons are typically associated only with radiative transfer between surfaces. Yet for over 70 years, the…

Understanding the flat thermal conductivity of La2Zr2O7 at ultrahigh temperatures
Hao Zhou, Janak Tiwari, Tianli Feng
Many crystals, such as lanthanum zirconate (La2Zr2O7), exhibit a flat temperature dependence of thermal conductivity at elevated temperatures. This phenomenon has recently been att…
