The acoustoelectric effect is the generation of a acoustoelectric current in a non-biased device by a piezoactive acoustic wave.This effect has recently attracted the attention of researchers as possible method to control the motion of massive objects in the quantum regime.We suggest use this effect for development of high sensitive nanoelectronic sensors.The sensitivity could be increase through the use of modulation mode of operation based on the acoustic pilot signal and the transition from quasi-stationary measurement to measurement at the modulation frequency.The acoustic delay line based on shear-horizontal acoustic wave of zero order (SH 0 ) with resonant frequency 2.77 MHz in Y-X LiNbO 3 plate was produced.The nanostructure consisting of nanowire with size 20nm x 180nm was placed in the center between IDTs.The volt-ampere characteristics of this nanowire in presence and at the absence of the acoustic wave were meazured by picoampermeter.The analysis has shown that presence of piezoactive acoustic wave is influenced on electric current in a nanowire.
