Abstract
We investigate the interaction between surface acoustic waves on a piezoelectric LiNbO3 substrate and charge carriers in InAs nanowire transistors. Interdigital transducers are used to excite electromechanical waves on the chip surface and their influence on the transport in the nanowire devices is studied at room temperature. Charge pumping is studied in different biasing conditions and in pulsed operation in order to assess interference effects due to reflected waves on the sample chip. Present results constitute a key building block for the realization of acoustoelectric nanodevices based on the InAs/InP nanowire technology.
