Entropy Driven Inductive Response of Topological Insulators
A. Mert Bozkurt, Sofie Kölling, Alexander Brinkman +1
3D topological insulators are characterized by an insulating bulk and extended surface states exhibiting a helical spin texture. In this work, we investigate the hyperfine interact…
Quantum Scars and Caustics in Majorana Billiards
R. Johanna Zijderveld, A. Mert Bozkurt, Michael Wimmer +1
We demonstrate that the classical dynamics influence the localization behaviour of Majorana wavefunctions in Majorana billiards. By using a connection between Majorana wavefunction…
Magnus effect on a Majorana zero-mode
G. Lemut, M. J. Pacholski, S. Plugge +2
A supercurrent on the proximitized surface of a topological insulator can cause a delocalization transition of a Majorana fermion bound to a vortex core as a zero-mode. Here we stu…
Heat transport and rectification via quantum statistical and coherence asymmetries
Stephania Palafox, Ricardo Román-Ancheyta, Barış Çakmak +1
Recent experiments at the nanoscales confirm that thermal rectifiers, the thermal equivalent of electrical diodes, can operate in the quantum regime. We present a thorough investig…
Dynamical Spin-Orbit-Based Spin Transistor
F. N. Gürsoy, P. Reck, C. Gorini +2
Spin-orbit interaction (SOI) has been a key tool to steer and manipulate spin-dependent transport properties in two-dimensional electron gases. Here we demonstrate how spin current…
Transformation of germanium to fluogermanates
S. Kalem, O. Arthursson, I. Romandic
The surface of a single crystal Germanium wafer was transformed to crystals of germanium fluorides and oxides upon exposure to a vapor of HF and HNO3 chemical mixture. Structure an…
Near-IR photoluminescence from Si/Ge nanowire grown silicon wafers: effect of HF treatment
Seref Kalem, Peter Werner, Vadim Talalaev
We present the room temperature (RT) near-infrared (NIR) photoluminescence (PL) properties of Si/Ge nanowire (NW) grown silicon wafers which were treated by vapor of HF:HNO3 chemic…
Photoluminescence from Silicon nanoparticles embedded in ammonium silicon hexafluoride
Seref Kalem, Peter Werner, Vadim Talalaev +3
Silicon (Si) nanoparticles (NPs) were synthesized by transforming Si wafer surface to ammonium silicon hexafluoride (ASH) or (NH4)2SiF6 under acid vapor treatment. Si-NPs are embed…
Controlling photon emission from silicon for photonic applications
Seref Kalem
The importance of a photon source that would be compatible with silicon circuitry is crucial for data communication networks. A photon source with energies ranging from UV to near…
Dynamics of parametric fluctuations induced by quasiparticle tunneling in superconducting flux qubits
M. Bal, M. H. Ansari, J. -L. Orgiazzi +2
We present experiments on the dynamics of a two-state parametric fluctuator in a superconducting flux qubit. In spectroscopic measurements, the fluctuator manifests itself as a dou…
Black Silicon with high density and high aspect ratio nanowhiskers
S Kalem, P Werner, Ö Arthursson +5
Physical properties of black Silicon (b-Si) formed on Si wafers by reactive ion etching in chlorine plasma are reported in an attempt to clarify the formation mechanism and the ori…
Chiral single-wall gold nanotubes
R. T. Senger, S. Dag, S. Ciraci
Based on first-principles calculations we show that gold atoms can form both free-standing and tip-suspended chiral single-wall nanotubes composed of helical atomic strands. Free-s…
