The tip of a scanning tunneling microscope is used to locally inject holes into the p-type side of green-emitting III-N light-emitting diode (LED) containing V-defects. The forward bias necessary to inject charge is 1 V lower on V-defect facets than on the LED's c-planes. This is the origin of record efficiencies in such LEDs.
