  • Publication number: 20140027808
    Abstract: A Si-based light emitting diode structure and a method for fabricating the Si-based light emitting diode structure are each predicated upon a multilayer material layer that comprises alternating, interposed and laminated sub-layers of: (1) a group IV nanocrystal material; and (2) an erbium or neodymium doped dielectric material. The light emitting diode structure is preferably laterally actuated to provide both efficient photoluminescence and electroluminescence. The group IV nanocrystal material may comprise a silicon nanocrystal material and the doped dielectric material may comprise an erbium doped silicon oxide material.

  • Patent number: 8518276
    Abstract: A process for forming a porous nanoscale membrane is described. The process involves applying a nanoscale film to one side of a substrate, where the nanoscale film includes a semiconductor material; masking an opposite side of the substrate; etching the substrate, beginning from the masked opposite side of the substrate and continuing until a passage is formed through the substrate, thereby exposing the film on both sides thereof to form a membrane; and then simultaneously forming a plurality of randomly spaced pores in the membrane. The resulting porous nanoscale membranes, characterized by substantially smooth surfaces, high pore densities, and high aspect ratio dimensions, can be used in filtration devices, microfluidic devices, fuel cell membranes, and as electron microscopy substrates.
