摘要： A nanowire light emitting diode (LED) and method of emitting light employ a plasmonic mode. The nanowire LED includes a nanowire having a semiconductor junction, a shell layer coaxially surrounding the nanowire, and an insulating layer, which is plasmonically thin, isolating the shell layer from the nanowire. The shell layer supports a surface plasmon that couples to the semiconductor junction by an evanescent field. Light is generated in a vicinity of the semiconductor junction and the surface plasmon is coupled to the semiconductor junction during light generation. The coupling enhances one or both of an efficiency of light emission and a light emission rate of the LED. A method of making the nanowire LED includes forming the nanowire, providing the insulating layer on the surface of the nanowire, and forming the shell layer on the insulating layer in the vicinity of the semiconductor junction.

摘要： Embodiments of the invention provide a method and an apparatus for performing self-aligned, sub-wavelength optical lithography. One embodiment provides a region of photoresist above a conductive surface having a plurality of periodically arrayed openings extending therethrough. At least a portion of the region of photoresist is then exposed to a light, wherein the intensity of the light is less than the intensity required to cure the photoresist. In so doing, at least one self-aligned, sub-wavelength location in at least one location of the region of photoresist is cured.
