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.…
Carrier diffusion in GaN -- a cathodoluminescence study. II: Ambipolar vs. exciton diffusion
Oliver Brandt, Vladimir M. Kaganer, Jonas Lähnemann +8
We determine the diffusion length of excess carriers in GaN by spatially resolved cathodoluminescence spectroscopy utilizing a single quantum well as carrier collector or carrier s…
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…
