A novel NPBL and ANPL light emitting semiconductor device and a method for fabricating the same are provided. In the present invention, plural nano-particles are applied in the active layer of the light emitting semiconductor device, so that the leakage current thereof is reduced. In addition, the provided light emitting semiconductor device fabricated via a planar technology process is microscopically planar, but not planar at micro- and nano-scale. Hence the parasitic wave guiding effect, which suppresses the light extraction efficiency of the light emitting semiconductor device, is destroyed thereby.

A composite, layered, integrated circuit formed by bonding of insulator layers on wafers provides for combination of otherwise incompatible technologies such as trench capacitor DRAM arrays and high performance, low power, low voltage silicon on insulator (SOI) switching transistors and short signal propagation paths between devices formed on respective wafer layers of a chip. In preferred embodiments, an SOI wafer is formed by hydrophilic bonding of a wafer over an integrated circuit device and then cleaving a layer of the second wafer away using implanted hydrogen and low temperature heat treatment. Further wafers of various structures and compositions may be bonded thereover and connections between circuit elements and connection pads in respective wafers made using short vias that provide fast signal propagation as well as providing more numerous connections than can be provided on chip edges.

A light source comprises: (a) a source of plasma discharge that emits electromagnetic radiation, a portion of which has wavelengths shorter than about 200 nm; and (b) a phosphor composition that comprises particles, each of the particles comprising at least a first phosphor and at least a second phosphor, the phosphor composition is disposed such that the first phosphor absorbs substantially the portion of EM radiation having wavelengths shorter than about 200 nm, and the first phosphor emits EM radiation having wavelengths longer than about 200 nm.

Single-molecule selection methods are provided for identifying target-binding molecules from diverse sequence and shape libraries. Complexes and imprints of selected target-binding molecules are also provided. The subject selection methods are used to identify oligonucleotide and nonnucleotide molecules with desirable properties for use in pharmaceuticals, drug discovery, drug delivery, diagnostics, medical devices, cosmetics, agriculture, environmental remediation, smart materials, packaging, microelectronics and nanofabrication. Single oligonucleotide molecules with desirable binding properties are selected from diverse sequence libraries and identified by amplification and sequencing. Alternatively, selected oligonucleotide molecules are identified by sequencing without amplification. Nonnucleotide molecules with desirable properties are identified by single-molecule selection from libraries of conjugated molecules or nucleotide-encoded nonnucleotide molecules. Alternatively, target-specific nonnucleotide molecules are prepared by imprinting selected oligonucleotide molecules into nonnucleotide molecular media. Complexes and imprints of molecules identified by single-molecule selection are shown to have broad utility as drugs, prodrugs, drug delivery systems, willfully reversible cosmetics, diagnostic reagents, sensors, transducers, actuators, adhesives, adherents and novel multimolecular devices.

A durable optical film or element includes a polymerized structure having a microstructured surface and a plurality of surface modified colloidal nanoparticles of silica, zirconia, or mixtures thereof. Display devices including the durable microstructured film are also described.
