GaN nanowire arrays for high-output nanogenerators.

Three-fold symmetrically distributed GaN nanowire (NW) arrays have been epitaxially grown on GaN/sapphire substrates. The GaN NW possesses a triangular cross section enclosed by (0001), (2112), and (2112) planes, and the angle between the GaN NW and the substrate surface is approximately 62 degrees . The GaN NW arrays produce negative output voltage pulses when scanned by a conductive atomic fo...
