摘要： An improved nanotip structure and method for forming the nanotip structure and a display system using the improved nanotip structure is described. The described nanotip is formed from a semiconductor having a crystalline structure such as gallium nitride. The crystalline structure preferably forms dislocations oriented in the direction of the nanotips. One method of forming the nanotip structure uses the relatively slow etching rates that occur around the dislocations compared to the faster etch rates that occur in other parts of the semiconductor structure. The slower etching around dislocations enables the formation of relatively high aspect ratio nanotips in the dislocation area.

摘要： A system comprises an electro-wetting subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electro-wetting subsystem comprises a photo-responsive photoreceptor, a charging mechanism, an image definition material reservoir, a charge erase mechanism, and an exposure subsystem, such as a light source and rotating polygon forming a raster output scanner (ROS) disposed for exposure of the photoreceptor through the image definition material reservoir. The imaging member comprises a reimageable surface having certain properties, such as having a low surface energy to promote ink release onto a substrate. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor, which is developed with image definition material. The image definition material pattern is transferred to the reimageable surface. The pattern is developed with ink. The inked image may be transferred to a substrate.

摘要： A system comprises an electrophotographic subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electrophotographic subsystem comprises a photoreceptor, a charging subsystem, an exposure subsystem, and a development subsystem. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor to thereby write a latent charge image onto the photoreceptor surface. The image is developed with an image defining material, such as a dampening fluid. The image defining material forms a negative pattern of the image to be printed. This negative image is then transferred to the reimageable surface. The negative image is then developed with ink. The inked image may be transferred to a substrate.

摘要： Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a surface of a porous substrate with radiation emitted by at least one radiant energy source. The radiation heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate.

摘要： In a variable data lithography system that employs a patterned dampening fluid layer for image formation, dampening fluid may be removed prior to image transfer to a substrate. Removed dampening fluid may be recovered and recycled to reduce operating expenses and environmental waste. A replacement fluid may be applied after inking and after removal of the dampening fluid. The replacement fluid preferentially occupies the regions previously occupied by dampening fluid, and may lubricate the transfer nip. Any replacement fluid and ink not transferred to the substrate upon printing may then be cleaned from the print image carrier prior to forming a new dampening fluid layer and subsequent pattern formation.

摘要： A xerographic micro-assembler system, method and apparatus that includes a sorting unit that is adapted to receive a plurality of micro-objects. The micro-objects can also be sorted and oriented on the sorting unit and then transferred to a substrate. The system, method and apparatus can also include a device for detecting errors in at least one of the micro-objects on the sorting unit and a protection means for preventing an improper micro-object from being transferred to the substrate. The system, method and apparatus can also include an organized micro-object feeder assembly that can transfer at least one of a plurality of micro-objects to the sorting unit or directly to the substrate.
