    Abstract: An apparatus and non-vapor-pressure dependent methods of producing silicon particles such as nanoparticles (Si-NPs), quantum dots (Si-QDs) and Si-nanocrystals (Si-NCs) as well as particle embedded thin films are disclosed. Nano or micro scale droplets of a liquid silane composition are polymerized in a gas phase with heat or radiation to produce particles that are then collected. Droplets from a droplet generator pass through a flow channel with a reaction zone that is heated or irradiated to form the particles that are collected in a collector. The flow of droplets may be assisted with carrier or flow gases that may be heated. Liquid silane composition solutions may also include metal, non-metal or metalloid dopants and solvents. Particle surfaces can also be passivated or functionalized. Particles and droplets of liquid silane can also be co-deposited and heated to produce particle embedded thin films.

    Abstract: An aerosol deposition system that uses a liquid ink, fed directly to an ultrasonic source at or near a nozzle to form an aerosolized ink, which may be transported via a carrier gas to a sheath gas insertion location is presented. The sheath gas may direct or focus the atomized ink through a nozzle. Alternatively, a deposition head may be adapted to the ultrasonic source so that aerosolization of the ink occurs inside the deposition head, where the sheath gas flows around the ultrasonic source, transporting the aerosolized ink through a nozzle and toward a substrate ˜2 mm distant. The substrate may be translated to form features of controlled shape such as lines with widths from ≦30 μm to 100 μm. Variations of this system may yield systems where a carrier gas is unnecessary, and all aerosolized ink is transported via the sheath gas.

    Abstract: Methods for producing surface functionalized silicon nanoparticles like Si-QDs using a continuous gas-phase synthesis by direct pyrolysis of aerosolized higher order liquid silanes like cyclohexasilane (Si6H12) or cyclopentasilane (Si5H10) to produce nanoscale particles are provided. The methods permit control over the particle characteristics i.e., crystallinity, core-shell, size and surface chemistry of Si nanostructures and allow the tuning of the band gap (absorption) and manipulation of photo responsive properties. A wide variety of modifications can be performed using the hydrogen (H) or hydroxyl (OH) groups attached to silicon atoms on the particle surface. The coupling of different molecules or complexes directly to the silicon atoms of the particles allows the engineering of desirable optical, chemical or biological activity to the particles or can act as linkers to agglomerate particles or form porous films.
