Magnetotransport in freely suspended two-dimensional electron systems for integrated nanomechanical resonators.
Physica E Low-dimensional Systems and Nanostructures 12 (1-4), pp. 487-490.
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 in standard magnetotransport measurements whereas the mechanical degrees of freedom are investigated in radio frequency resonance experiments. The interplay of both can be exploited for ultrasensitive displacement detection.
