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…
Accurate prediction of thermal conductivity of Al2O3 at ultrahigh temperatures
Janak Tiwari, Tianli Feng
Many complex crystals show a flattening or even increasing lattice thermal conductivity at high temperatures, which deviates from the traditional 1/T decay trend given by conventio…
Intrinsic thermal conductivity of ZrC from low to ultra-high temperatures: A critical revisit
Janak Tiwari, Tianli Feng
Current phonon transport theory based on ground-state calculations has been successful in predicting thermal conductivity at room and medium temperatures but may misrepresent behav…
High Thermal Conductivity in Wafer Scale Cubic Silicon Carbide Crystals
Zhe Cheng, Jianbo Liang, Keisuke Kawamura +7
High thermal conductivity electronic materials are critical components for high-performance electronic and photonic devices as either active functional materials or thermal managem…
