CMOS Platform for Atomic-Scale Device Fabrication
Tomas Skeren, Nikola Pascher, Arnaud Garnier +6
Controlled atomic scale fabrication of functional devices is one of the holy grails of nanotechnology. The most promising class of techniques that enable deterministic nanodevice f…
Characterization of Hydrogen Plasma Defined Graphene Edges
Mirko K. Rehmann, Yemliha B. Kalyoncu, Marcin Kisiel +8
We investigate the quality of hydrogen plasma defined graphene edges by Raman spectroscopy, atomic resolution AFM and low temperature electronic transport measurements. The exposur…
Tunnel barrier design in donor nanostructures defined by hydrogen-resist lithography
Nikola Pascher, Szymon Hennel, Susanne Mueller +1
A four-terminal donor quantum dot (QD) is used to characterize potential barriers between degenerately doped nanoscale contacts. The QD is fabricated by hydrogen-resist lithography…
Resonant electron tunneling in a tip-controlled potential landscape
N. Pascher, F. Timpu, C. Rossler +4
By placing the biased tip of an atomic force microscope at a specific position above a semiconductor surface we can locally shape the potential landscape. Inducing a local repulsiv…
Imaging the Conductance of Integer and Fractional Quantum Hall Edge States
Nikola Pascher, Clemens Rössler, Thomas Ihn +3
We measure the conductance of a quantum point contact (QPC) while the biased tip of a scanning probe microscope induces a depleted region in the electron gas underneath. At finite…
Electron spin resonance in Eu based Fe pnictides
H. -A. Krug von Nidda, S. Kraus, S. Schaile +9
The phase diagrams of EuFeCoAs and EuFeAsP are investigated by Eu electron spin resonance (ESR)…
Orbital fluctuations and orbital order below the Jahn-Teller transition in Sr3Cr2O8
Zhe Wang, M. Schmidt, A. Günther +10
We report on the magnetic and phononic excitation spectrum of Sr3Cr2O8 determined by THz and infrared (IR) spectroscopy, and electron spin resonance (ESR) measurements across the J…
Magnetic fluctuations and superconductivity in Fe pnictides probed by electron spin resonance
N. Pascher, J. Deisenhofer, H. -A. Krug von Nidda +4
The electron spin resonance absorption spectrum of Eu^{2+} ions serves as a probe of the normal and superconducting state in Eu_{0.5}K_{0.5}Fe_2As_2. The spin-lattice relaxation ra…
