Remote Surface Optical Phonon Scattering in Ferroelectric BaSrTiO Gated Graphene
Hanying Chen, Tianlin Li, Yifei Hao +5
We report the effect of remote surface optical (RSO) phonon scattering on carrier mobility in monolayer graphene gated by ferroelectric oxide. We fabricate monolayer graphene trans…
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…
Infrared dielectric functions and Brillouin zone center phonons of -GaO compared to -AlO
Megan Stokey, Rafal Korlacki, Matthew Hilfiker +11
We determine the anisotropic dielectric functions of rhombohedral -GaO by far-infrared and infrared generalized spectroscopic ellipsometry and derive all transverse opti…
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…
Broadband enhanced chirality with tunable response in hybrid plasmonic helical metamaterials
Ufuk Kilic, Matthew Hilfiker, Alexander Ruder +4
Designing broadband enhanced chirality is of strong interest to the emerging fields of chiral chemistry and sensing, or to control the spin orbital momentum of photons in recently…
Anisotropic dielectric functions, band-to-band transitions, and critical points in α-Ga2O3
Matthew Hilfiker, Rafał Korlacki, Riena Jinno +6
We use a combined generalized spectroscopic ellipsometry and density functional theory approach to determine and analyze the anisotropic dielectric functions of an -GaO…
