20110233382 | Method and Apparatus for High Resolution Photon Detection Based on Extraordinary Optoconductance (EOC) Effects - The inventors disclose a new high performance optical sensor, preferably of nanoscale dimensions, that functions at room temperature based on an extraordinary optoconductance (EOC) phenomenon, and preferably an inverse EOC (I-EOC) phenomenon, in a metal-semiconductor hybrid (MSH) structure having a semiconductor/metal interface. Such a design shows efficient photon sensing not exhibited by bare semiconductors. In experimentation with an exemplary embodiment, ultrahigh spatial resolution 4-point optoconductance measurements using Helium-Neon laser radiation reveal a strikingly large optoconductance property, an observed maximum measurement of 9460% EOC, for a 250 nm device. Such an exemplary EOC device also demonstrates specific detectivity higher than 5.06×10 | 09-29-2011 |

20090142936 | METHOD OF FORMING GATED, SELF-ALIGNED MICRO-STRUCTURES AND NANO-STRUCTURES - Methods of forming a gated, self-aligned nano-structures for electron extraction are disclosed. One method of forming the nano-structure comprises irradiating a first surface of a thermally conductive laminate to melt an area across the first surface of the laminate. The laminate comprises a thermally conductive film and a patterned layer disposed on the first surface of the film. The patterned layer has a pattern formed therethrough, defining the area for melting. The film is insulated at a second surface thereof to provide two-dimensional heat transfer laterally in plane of the film. The liquid density of the film is greater than the solid density thereof. The method further comprises cooling the area inwardly from the periphery thereof to form the nano-structure having an apical nano-tip for electron emission centered in an electrically isolated aperture that serves as a gate electrode to control electron extraction in a gated field emitter device. | 06-04-2009 |
20100043881 | TITANIUM DIOXIDE THIN FILM SYSTEMS AND METHOD OF MAKING SAME - A method for producing a thin film titanium dioxide is disclosed. The disclosed method for producing the thin film titanium dioxide includes performing a magnetron reactive sputtering process to vaporize at least portions of a titanium source in a sputtering chamber that is supplied with gaseous oxygen. The vaporized titanium reacts with the oxygen to form anatase titanium dioxide, which is deposited on a substrate within the sputtering chamber. | 02-25-2010 |
20140027201 | ACOUSTIC METAMATERIALS - Metamatenal members for absorbing sound and pressure, and modular systems built of metamaterial members are provided. The metamaterial member includes an outer mass. The outer mass can have a cavity formed therein in which a stem coupled to an inner mass is disposed, or the outer mass can be solid and contain an inner mass embedded therein. The inner mass can include an inner core and an outer shell. Multiple metamaterial members can be attached to form a modular system for absorption of sound and pressure. | 01-30-2014 |

20150197068 | METHOD OF MAKING COMPOSITE MATERIALS - A method of making a hybrid material is described. The hybrid material comprises a metal substrate layer, a carbon fiber composite layer, and an adhesive layer. The adhesive layer may be a foam adhesive. The adhesive layer minimizes thermal distortion of the metal substrate layer and the carbon fiber composite layer such that both layers experience less than 5% out-of-plane distortion. | 07-16-2015 |
