Thermal shift of the resonance between an electron gas and quantum dots: What is the origin?
Fabian Brinks, Andreas D. Wieck, Arne Ludwig
The operation of quantum dots at highest possible temperatures is desirable for many applications. Capacitance-voltage spectroscopy (C(V)-spectroscopy) measurements are an establis…
Development of Yttrium alloy ion source and its application in nanofabrication
Nadezhda Kukharchyk, Ronna Neumann, Swetlana Mazarov +3
We present a new YAuSi Liquid Metal Alloy Ion Source (LMAIS), generating focused ion beams of yttrium ions, and its prospective applications for nanofabrication, sample preparation…
Fast probe of local electronic states in nanostructures utilizing a single-lead quantum dot
Tomohiro Otsuka, Shinichi Amaha, Takashi Nakajima +8
Transport measurements are powerful tools to probe electronic properties of solid-state materials. To access properties of local electronic states in nanostructures, such as local…
Tunneling induced spin dynamics in a quantum dot-lead hybrid system
Tomohiro Otsuka, Takashi Nakajima, Matthieu R. Delbecq +11
Semiconductor quantum dots (QDs) offer a platform to explore the physics of quantum electronics including spins. Electron spins in QDs are considered good candidates for quantum bi…
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…
Photoelectron generation and capture in the resonance fluorescence of a quantum dot
Annika Kurzmann, Arne Ludwig, Andreas D. Wieck +2
Time-resolved resonance fluorescence (RF) on a single self-assembled quantum dot (QD) is used to analyze the generation and capture of photoinduced free charge carriers. We directl…
