Anisotropic Anharmonicity Dictates the Thermal Conductivity of Gallium Oxide ($\beta -G{a}_2{O}_3$)

Abdulaziz Alkandari, Zherui Han, Ziqi Guo +2

$\beta -G{a}_2{O}_3$ is a promising material candidate for next-generation high power devices even as its low thermal conductivity ($\kappa$) limits utilization due to an inability to sufficient…
