This paper demonstrates the manipulation of neutral dielectric wires with high aspect ratio by a pulsed electric field. Dielectrophoretic (DEP) force and torque were employed to align the randomly positioned GaN nano- and micro-wires. A simulation of the DEP force alignment process confirmed the experimentally observed dependence on alignment yield to frequency and bias of the electric field. Current-voltage measurements of the GaN micro-wires, aligned by DEP force and torque to pre-patterned metal contacts, confirms that the direct manipulation of micro-sized wire with an electric field oscillated at a frequency of 10 kHz-5 MHz.
