The properties of the
hybrid energy sources “piezoelectric nanogenerator-solar cell” based on GaAs
nanowires with the wurtzite crystal structure were investigated. Measurements
were performed by the bending of the nanowire by the probe of the atomic force microscope
with simultaneous recording of short circuit current in dark and illuminated
conditions. We show that a piezoelectric current pulse of ~10 pA arises in the
“nanowire-probe” circuit during the deformation of nanowire by the AFM probe.
Under laser illumination, the value of the pulse increases by two orders of
magnitude as a result of the piezophototronic effect. Deformation of the
nanowire boosts the photocurrent by 40% up to 0.5 nA.
