Optical Visualization of Radiative Recombination at Partial Dislocations in GaAs
Todd Karin, Xiayu Linpeng, Ashish K. Rai +3
Individual dislocations in an ultra-pure GaAs epilayer are investigated with spatially and spectrally resolved photoluminescence imaging at 5~K. We find that some dislocations act…
Coherent electron-spin-resonance manipulation of three individual spins in a triple quantum dot
Akito Noiri, Jun Yoneda, Takashi Nakajima +8
Quantum dot arrays provide a promising platform for quantum information processing. For universal quantum simulation and computation, one central issue is to demonstrate the exhaus…
Focused ion beam induced growth of monocrystalline InAs nanowires
S. Scholz, R. Schott, P. A. Labud +4
We investigate monocrystalline InAs nanowires (NWs) which are grown by molecular beam epitaxy (MBE) and induced by focused ion beam (FIB) implanted Au spots. With this unique combi…
Strong Coupling of Intersubband Resonance in a High Electron Mobility Transistor Structure to a THz Metamaterial by Ultrawide Electrical Tuning
Shovon Pal, Hanond Nong, Sergej Markmann +8
The interaction between intersubband resonances (ISRs) and metamaterial microcavities can form a strongly coupled system where new resonances form that depend on the coupling stren…
