A 3.5-THz, x6-Harmonic, Single-Ended Schottky Diode Mixer for Frequency Stabilization of Quantum-Cascade Lasers
Divya Jayasankar, Vladimir Drakinskiy, Nick Rothbart +8
Efficient and compact frequency converters are essential for frequency stabilization of terahertz sources. In this paper, we present a 3.5-THz, x6-harmonic, integrated Schottky dio…
Drastic effect of sequential deposition resulting from flux directionality on the luminescence efficiency of nanowire shells
Hanno Küpers, Ryan B. Lewis, Pierre Corfdir +6
Core-shell nanowire heterostructures form the basis for many innovative devices. When compound nanowire shells are grown by directional deposition techniques, the azimuthal positio…
Coherence Resonance and Stochastic Resonance in an Excitable Semiconductor Superlattice
Emanuel Mompo, Miguel Ruiz Garcia, Manuel Carretero +3
Collective electron transport causes a weakly coupled semiconductor superlattice under dc voltage bias to be an excitable system with degrees of freedom: electron densities…
Electronic and magnetic properties of -FeGe films embedded in vertical spin valve devices
Dietmar Czubak, Samuel Gaucher, Lars Oppermann +5
We studied metastable -FeGe, a novel layered tetragonal material, embedded as a spacer layer in spin valve structures with ferromagnetic FeSi and CoFeSi electrodes.…
Enhanced radiative efficiency in GaN nanowires grown on sputtered TiN: effects of surface electric fields
T. Auzelle, M. Azadmand, T. Flissikowski +8
GaN nanowires grown by molecular beam epitaxy generally suffer from dominant nonradiative recombination, which is believed to originate from point defects. To suppress the formatio…
Absence of quantum-confined Stark effect in GaN quantum disks embedded in (Al,Ga)N nanowires grown by molecular beam epitaxy
C. Sinito, P. Corfdir, C. Pfüller +14
Several of the key issues of planar (Al,Ga)N-based deep-ultraviolet light emitting diodes could potentially be overcome by utilizing nanowire heterostructures, exhibiting high stru…
