Research Focus
Organic light-emitting devices (OLEDs) were fabricated on scanning probe cantilevers(a) using a combination of thermally evaporated molecular organic compounds and metallic electrodes. Ion beam lithography was used to define the emissive region in the shape of a ring having a diameter of less than 5 micrometers and a narrow width. Stable light emission(b) was observed from the device at forward bias, with a current-voltage response(c) similar to that of archetypal OLEDs. Based on this device, a novel electrically-pumped scanning optical microscopy tool is suggested.
