An in-situ tunable radio-frequency quantum point contact
Thomas Müller, Bruno Küng, Paul Studerus +5
Incorporating a variable capacitance diode into a radio-frequency matching circuit allows us to in-situ tune the resonance frequency of an RF quantum point contact, increasing the…
Quantum capacitance and density of states of graphene
S. Dröscher, P. Roulleau, F. Molitor +4
We report on measurements of the quantum capacitance in graphene as a function of charge carrier density. A resonant LC-circuit giving high sensitivity to small capacitance changes…
Counting statistics and super-Poissonian noise in a quantum dot
S. Gustavsson, R. Leturcq, B. Simovic +6
We present time-resolved measurements of electron transport through a quantum dot. The measurements were performed using a nearby quantum point contact as a charge detector. The ra…
Design of Q-Band loop-gap resonators at frequencies 34-36 GHz for single electron spin spectroscopy in semiconductor nanostructures
B. Simovic, P. Studerus, S. Gustavsson +5
We report on the design of loop-gap resonators (LGR) operating in the frequency range 34-36 GHz with the goal to achieve single electron spin resonance (ESR) in quantum dot nanostr…
Local oxidation of Ga[Al]As heterostructures with modulated tip-sample voltages
D. Graf, M. Frommenwiler, P. Studerus +4
Nanolithography based on local oxidation with a scanning force microscope has been performed on an undoped GaAs wafer and a Ga[Al]As heterostructure with an undoped GaAs cap layer…
Operating a phase-locked loop controlling a high-Q tuning fork sensor for scanning force microscopy
T. Ihn, T. Vancura, A. Baumgartner +2
The implementation of a tuning fork sensor in a scanning force microscope operational at 300 mK is described and the harmonic oscillator model of the sensor is motivated. These sen…
