The underlying V a waveform is a =1 Hz triangle wave with 200 V pp . 1emission modulation is observed for both single nanowires and with multiple nanowires within the same field of view. The first movie (MOV_wire 62_regular_bias.avi) illustrates the magnitude of the modulation in a single wire. The second movie (MOV_wire27_regular bias.avi) shows synchronous modulation of two wires in the field of view.
