Lattice anharmonicity effects in fluorite oxide single crystals and anomalous increase in phonon lifetime in ceria at elevated temperature Open
We investigate the temperature dependence of the frequency and linewidth of the triply-degenerate T$_{2g}$ zone-centered optical phonon in flux-grown ceria and hydrothermally-synthesized thoria single crystals from room temperature to 1273…

Si content variation and influence of deposition atmosphere in homoepitaxial Si-doped β-Ga<sub>2</sub>O<sub>3</sub> films by pulsed laser deposition Open
Carrier concentration control by impurity dopants in epitaxial Ga2O3 thin films is progressing to deliver high mobility films for device structures. Si-doped Ga2O3 thin films were fabricated by pulsed laser deposition on (010) β-Ga2O3 subs…

Incomplete Ionization of a 110 meV Unintentional Donor in β-Ga2O3 and its Effect on Power Devices Open
Understanding the origin of unintentional doping in Ga 2 O 3 is key to increasing breakdown voltages of Ga 2 O 3 based power devices. Therefore, transport and capacitance spectroscopy studies have been performed to better understand the or…
