Abstract: Silicon nanoparticle inks provide a basis for the formation of desirable materials. Specifically, composites have been formed in thin layers comprising silicon nanoparticles embedded in an amorphous silicon matrix, which can be formed at relatively low temperatures. The composite material can be heated to form a nanocrystalline material having crystals that are non-rod shaped. The nanocrystalline material can have desirable electrical conductive properties, and the materials can be formed with a high dopant level. Also, nanocrystalline silicon pellets can be formed from silicon nanoparticles deposited form an ink in which the pellets can be relatively dense although less dense than bulk silicon. The pellets can be formed from the application of pressure and heat to a silicon nanoparticle layer.

Abstract: Submicron powders of metal silicon nitrides and metal silicon oxynitrides are synthesized using nanoscale particles of one or more precursor materials using a solid state reaction. For example, nanoscale powders of silicon nitride are useful precursor powders for the synthesis of metal silicon nitride and metal silicon oxynitride submicron powders. Due to the use of the nanoscale precursor materials for the synthesis of the submicron phosphor powders, the product phosphors can have very high internal quantum efficiencies. The phosphor powders can comprise a suitable dopant activator, such as a rare earth metal element dopant.

In some embodiments, an intrinsic layer can be a composite of an amorphous silicon portion and a crystalline silicon portion.

Abstract: Improved silicon/germanium nanoparticle inks are described that have silicon/ germanium nanoparticles well distributed within a stable dispersion. In particular the inks are formulated with a centrifugation step to remove contaminants as well as less well dispersed portions of the dispersion. A sonication step can be used after the centrifugation, which is observed to result in a synergistic improvement to the quality of some of the inks. The silicon/germanium ink properties can be engineered for particular deposition applications, such as spin coating or screen printing. Appropriate processing methods are described to provide flexibility for ink designs without surface modifying the silicon/germanium nanoparticles. The silicon/germanium nanoparticles are well suited for forming semiconductor components, such as components for thin film transistors or solar cell contacts.
