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…
Impacts of Point Defects on Shallow Doping in Cubic Boron Arsenide: A First Principles Study
Shuxiang Zhou, Zilong Hua, Kaustubh K. Bawane +2
Cubic boron arsenide (BAs) stands out as a promising material for advanced electronics, thanks to its exceptional thermal conductivity and ambipolar mobility. However, effective co…
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…
Ruddlesden-Popper chalcogenides push the limit of mechanical stiffness and glass-like thermal conductivity in single crystals
Md Shafkat Bin Hoque, Eric R. Hoglund, Boyang Zhao +20
Insulating materials featuring ultralow thermal conductivity for diverse applications also require robust mechanical properties. Conventional thinking, however, which correlates st…
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…
