Nanoscale origin of thermal anisotropy in monoclinic \texorpdfstring{ $β$ -Ga $_{2}$ O $_{3}$ }{beta-Ga2O3}

Kai Xu, Shuo Zhao, Luca Sung-Min Choi +19

Monoclinic $β$ -Ga $_{2}$ O $_{3}$ is a promising ultra-wide-bandgap semiconductor for power electronics, but its low and anisotropic thermal conductivity limits heat removal, making it a…

$β$ -Ga $_{2}$ O $_{3}$ (001) surface reconstructions from first principles and experiment

Konstantin Lion, Piero Mazzolini, Kingsley Egbo +4

We present a comprehensive investigation of reconstructions on $β$ -Ga $_{2}$ O $_{3}$ (001) combining first-principles calculations with experimental observations. Using ab initio atomisti…

Spectral tuning of hyperbolic shear polaritons in monoclinic gallium oxide via isotopic substitution

Giulia Carini, Mohit Pradhan, Elena Gelzinyte +26

Hyperbolic phonon polaritons - hybridized modes arising from the ultrastrong coupling of infrared light to strongly anisotropic lattice vibrations in uniaxial or biaxial polar crys…
