Free-standing beams containing a two-dimensional electron system are shaped from a GaAs/ AlGaAs heterostructure. Quantum point contacts and ( double) quantum dots are laterally defined using metal top gates. We investigate the electronic properties of these nanostructures by transport spectroscopy. Tunable localized electron states in freely suspended nanostructures are a promising tool to investigate the electron-phonon interaction.
