N1 - The work is supported by the Russian Science Foundation (Grant No. 22-12-00343\u2014experimental measurements and theoretical simulation) and the Ministry of Science and Higher Education of The Russian Federation (Project No. FWGW-2022-0011\u2014characterization of the initial structures). Electron beam lithography was done using the equipment of CKP \u201CVTAN\u201D in the ATRC department of NSU.

N2 - In a nanomechanical resonator coupled to a quantum point contact, the back action of the electronic state on mechanical motion is studied. The quantum point contact conductance changing with subband index and the eigenfrequency of the resonator are found to correlate. A model is constructed explaining the frequency deviations by the variable ability of the quantum point contact to screen the piezoelectric charge induced by mechanical oscillations. The observed effects can be used to develop electromechanical methods for studying the density of states in quasi-one-dimensional systems.
