Low-temperature, in situ tunable, uniaxial stress measurements in semiconductors using a piezoelectric actuator
M. Shayegan, K. Karrai, Y. P. Shkolnikov +3
We demonstrate the use of a piezoelectric actuator to apply, at low temperatures, uniaxial stress in the plane of a two-dimensional electron system confined to a modulation-doped A…
Periodic Field Emission from an Isolated Nano-Scale Electron Island
D. V. Scheible, C. Weiss, J. P. Kotthaus +1
We observe field emission from an isolated nano-machined gold island. The island is able to mechanically oscillate between two facing electrodes, which provide recharging and detec…
Slow two-level systems in point contacts
A. Halbritter, L. Borda, A. Zawadowski
A great variety of experiments, like heat release measurements, acoustic measurements, and transport measurements on mesoscopic samples have proved that two level systems (TLSs) ha…
Gate-controlled spin-splitting in quantum dots with ferromagnetic leads in the Kondo regime
J. Martinek, M. Sindel, L. Borda +6
The effect of a gate voltage () on the spin-splitting of an electronic level in a quantum dot (QD) attached to ferromagnetic leads is studied in the Kondo regime using a gener…
Observation of single defect relaxation in a freely suspended nano resonator
Florian W. Beil, Robert H. Blick, Achim Wixforth +3
Relaxation of single defects in a nanometer sized resonator is observed by coupling surface acoustic waves to a freely suspended beam. The surface waves act on the resonator as dri…
Theory of inelastic scattering from magnetic impurities
G. Zarand, L. Borda, Jan von Delft +1
We use the numerical renormalization group method tocalculate the single particle matrix elements of the many body -matrix of the conduction electrons scattered by a ma…
