Terahertz electron paramagnetic resonance generalized spectroscopic ellipsometry: The magnetic response of the nitrogen defect in 4H-SiC
Mathias Schubert, Sean Knight, Steffen Richter +8
We report on terahertz (THz) electron paramagnetic resonance generalized spectroscopic ellipsometry (THz-EPR-GSE). Measurements of the field and frequency dependencies of the magne…
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…
Thermal conductivity of bulk InO single crystals
Liangcai Xu, Benoit Fauqué, Zengwei Zhu +3
The transparent semiconductor InO is a technologically important material. It combines optical transparency in the visible frequency range and sizeable electric conduct…
Carbon doping of GaN: Proof of the formation of electrically active tri-carbon defects
Ivan Gamov, Eberhard Richter, Markus Weyers +10
Carbon doping is used to obtain semi-insulating GaN crystals. If the carbon doping concentration exceeds , the carbon atoms increasingly form triatomic cluster…
