Tunable cavity-enhanced terahertz frequency-domain optical Hall effect
Sean Knight, Stefan Schöche, Philipp Kühne +3
Presented here is the development and demonstration of a tunable cavity-enhanced terahertz frequency-domain optical Hall effect technique. The cavity consists of at least one fixed…
Infrared dielectric function, phonon modes and free-charge carrier properties of high-Al-content AlGaN alloys determined by mid-infrared spectroscopic ellipsometry and optical Hall effect
S. Schöche, T. Hofmann, D. Nilsson +6
The phonon mode parameters and anisotropic mid-infrared dielectric function tensor components of high- Al-content AlGaN alloys in dependence of the Al content are p…
Cavity-enhanced optical Hall effect in two-dimensional free charge carrier gases detected at terahertz frequencies
S. Knight, S. Schöche, V. Darakchieva +6
The effect of a tunable, externally coupled Fabry-Pérot cavity to resonantly enhance the optical Hall effect signatures at terahertz frequencies produced by a traditional Drude-lik…
Free-charge carrier parameters of n-type, p-type and compensated InN:Mg determined by Infrared Spectroscopic Ellipsometry
S. Schöche, T. Hofmann, V. Darakchieva +6
Infrared spectroscopic ellipsometry is applied to investigate the free-charge carrier properties of Mg-doped InN films. Two representative sets of In-polar InN grown by molecular b…
Electron effective mass in AlGaN alloys determined by mid-infrared optical Hall effect
S. Schöche, P. Kühne, T. Hofmann +5
The effective electron mass parameter in Si-doped AlGaN is determined to be from mid-infrared optical Hall effect measurements. No s…
