Abstract. A quantitative physical model, describing the piezoelectric electromechanical coupling in nanomechanical resonators with a two-dimensional electron gas, is developed. Numerical calculations of the change in density of a two-dimensional electron gas contained in a vibrating cantilever are performed using the model and are shown to be consistent with the experiment. The obtained data show that the vibration-induced electron density modulation is localized near the clamping point and that it is related to a rapid spatial change in the mechanical stress near this point. It is shown that details of the clamping geometry significantly affect the magnitude of the effect.

Short summary
The low-dimensional electron systems made from semiconductor heterostructures are known mostly as a base for studying the mesoscopic electron-transport phenomena. However, they can also be used for creation of nanoelectromechanical systems combining non-trivial electron transport and mechanical degrees of freedom. In the present paper, we propose a quantitative physical model describing the piezoelectric electromechanical coupling in nanomechanical resonators with a two-dimensional electron gas.
