A quantum dot is created within a suspended nanobridge containing a two-dimensional electron gas. The electron current through this dot exhibits well-pronounced Coulomb blockade oscillations. When surface acoustic waves (SAW) are driven through the n

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 driving forces being able to modify the internal friction in the beam. In

A nanomechanical beam resonator is used to image the standing wave pattern formed by two counter propagating surface acoustic waves of the Rayleigh type. As the intrinsic properties of the resonator are affected by a fast off-resonant mechanical exci

We present magnetotransport measurements on freely suspended two-dimensional electron gases. Samples are prepared from GaAs/AlGaAs-heterostructures containing an additional sacrificial layer. The electronic properties of the system are characterized

We study the formation of shock waves in a suspended two-dimensional electron gas using surface acoustic waves. The mechanical displacement of the nano-resonator is read out via the induced acoustoelectric current. Applying acoustical standing waves,

The dream of every surfer is an extremely steep wave propagating at the highest speed possible. The best waves for this would be shock waves, but are very hard to surf. In the nanoscopic world the same is true: the surfers in this case are electrons

For a variety of applications in integrated communication and sensor devices nano-electromechanical systems (NEMS) present a new generation of high frequency components. Up to now conventional excitation mechanisms for NEMS are based either on high m

We realize nanomechanical resonators for studying their mechanical properties in the nonlinear regime. This is of prime importance considering signal mixing which is a direct result of nonlinear mechanical response. Combining signal mixing with the a

A new method to optically examine surface acoustic wave (SAW) propagation on a semiconductor chip is presented. This visualization method is based on the influence of a SAW on the optical properties of a piezoelectric semiconductor. There are two int
