First and Second Order Raman Spectroscopy of Monoclinic
Benjamin M. Janzen, Roland Gillen, Zbigniew Galazka +2
We employ a combined experimental-theoretical study of the first- and second-order Raman modes of monoclinic -GaO. The investigated materials is of particular intere…
A consistent picture of excitations in cubic BaSnO revealed by combining theory and experiment
Wahib Aggoune, Alberto Eljarrat, Dmitrii Nabok +6
Among the transparent conducting oxides, the perovskite barium stannate is most promising for various electronic applications due to its outstanding carrier mobility achieved at ro…
Optical phonon modes, static and high frequency dielectric constants, and effective electron mass parameter in cubic InO
Megan Stokey, Rafal Korlacki, Sean Knight +8
A complete set of all optical phonon modes predicted by symmetry for bixbyite structure indium oxide is reported here from a combination of far-infrared and infrared spectroscopic…
Fingerprints of optical absorption in the perovskite LaInO: Insight from many-body theory and experiment
Wahib Aggoune, Klaus Irmscher, Dmitrii Nabok +5
We provide a combined theoretical and experimental study of the electronic structure and the optical absorption edge of the orthorhombic perovskite LaInO. Employing density-f…
The anisotropic quasi-static permittivity of single-crystal beta-Ga2O3
Prashanth Gopalan, Sean Knight, Ashish Chanana +11
The quasi-static anisotropic permittivity parameters of electrically insulating gallium oxide (beta-Ga2O3) were determined by terahertz spectroscopy. Polarization-resolved frequenc…
Offcut-related step-flow and growth rate enhancement during (100) -Ga2O3 homoepitaxy by metal-exchange catalyzed molecular beam epitaxy (MEXCAT-MBE)
Piero Mazzolini, Andreas Falkenstein, Zbigniew Galazka +2
In this work we investigate the growth of -Ga2O3 homoepitaxial layers on top of (100) oriented substrates via indium-assisted metal exchange catalyzed molecular beam epitaxy (ME…
