摘要:
The present disclosure is drawn to electrostatic printing. In an example, a coated photoconductive substrate can comprise a photoconductive substrate, the photoconductive substrate including a substrate having a charge generation layer and charge transport layer adhered thereto; and a top coating adhered to the photoconductive substrate. The top coating can comprise a cross-linkable polymer, a cross-linker, and a charge transport material, where the charge transport material is dispersed throughout the top coating and may be present in the top coating in an amount ranging from 20 wt % to 50 wt %.

A method for making a photoconductor for electrophotography can comprise depositing a charge generating layer on an electrode; depositing a charge transfer layer on the charge generating layer, where a plurality of charge transfer molecules are disposed within the charge transfer layer; depositing a film of non-conducting material onto the surface of the charge-transfer layer; heating the film and the surface to cause a subset of the charge transfer molecules to move into the non-conducting material, creating in the film a conducting sub-layer and an insulating sub-layer, where the insulating sub-layer is substantially free of charge transfer molecules.

A light emitting system includes a polymer mixture, and a plurality of nanocrystals occupying a predetermined portion of the polymer mixture. The polymer mixture includes at least two polymers that phase-segregate. Method(s) for controlling nanocrystal distribution within the light emitting device are also disclosed.
摘要:
In a method of forming a conductive path on a substrate, a layer of metallic nanoparticles is printed on the substrate and a conductive organic material is also printed, such that the conductive organic material is interspersed with the layer of metallic nanoparticles to thereby enhance one or more electrical properties of the conductive path.

A system comprises a processing chamber for maintaining a hydrogen plasma at low pressure. The processing chamber has a long, wide, thin geometry to favor deposition of thin-film silicon on sheet substrates over the chamber walls. The sheet substrates are moved through between ends. A pair of opposing radio frequency electrodes above and below the workpieces are electrically driven hard to generate a flat, pancaked plasma cloud in the middle spaces of the processing chamber. A collinear series of gas injector jets pointed slightly up on a silane-jet manifold introduce 100% silane gas at high velocity from the side in order to roll the plasma cloud in a coaxial vortex. A second such silane-jet manifold is placed on the opposite side and pointed slightly down to further help roll the plasma and maintain a narrow band of silane concentration. A silane-concentration monitor observes the relative amplitudes of the spectral signatures of the silane and the hydrogen constituents in the roll-vortex plasma and outputs a process control feedback signal that is used to keep the silane in hydrogen concentration at about 6-7%.
