The invention is a general design for a simultaneously emitting, dual wavelength diode laser for electronically simpler and more efficient remote sensing (e.g., water vapor on Mars, wind/weather analy
This invention is a method for the continuous production of semiconductor nanoparticles (i.e. quantum dots), nanostrucutured catalysts, nanostructured metals and metal oxides, and ceramic oxide nanoparticles using ultrasonically generated aerosols of high boiling point solvents.
This technology is a powerful new route to the manufacturing of high performance thin film transistors on plastic substrates. Free standing micro and nanoscale objects of single crystal silicon can be fabricated from bulk silicon or silicon on insulator wafers by lithographic patterning of resist, etching of the exposed top silicon, and removing the underlying SiO2 to liftoff the remaining silicon. This form of "top down" microtechnology represents an attractive route to high performance flexible electronic systems.
This invention allows for the production of a family of photodetectors that are sensitive in the ultraviolet, visible, and near-infrared regions of the spectrum.
These technologies include three inventions that can work independently or that can be integrated to address problems with sensing and monitoring in a wide variety of industries, including military, medical and robotics. Each of the three inventions confronts a specific set of problems:
Artificial Hair Cell Sensor is a method for designing and fabricating arrayed artificial cilia-type micro-sensors in flexible substrates.
This invention increases a narrow stripe laser's power while maintaining its single mode nature by making the laser wider.
This technology maximizes a semiconductor laser's optical mode overlap and injected carriers. The semiconductor laser's optical mode overlap is optimized with the gain to produce lasers with lower threshold currents than standard ridge waveguide (RW) lasers.
A separate lateral confinement (SLC) structure creates a clear reduction in lasing threshold that is possible because of confinement of the injected carriers.
This technology provides a technique for fabricating metallic structures with dimensions considerably smaller than 10 nm and the use of a focused electron beam to locally manipulate nanowires with a resolution of about 3 nm. This is the first technology to use an electron beam and achieve such a high resolution of matter manipulation.
This technology allows significant advances in the application of sensing technology. The invention is a method for more efficiently creating superior substrates that are flexible in three dimensions and can be worn, attached to moving objects, or used to produce truly flexible displays.
This invention is a novel multifunctional probe array that allows for both dip-pen nanolithography (DPN) and scanning probe contact printing (SPCP) along with a dedicated imaging tip. Each probe can be independently lifted from the substrate surface, so that either a writing or imaging tip is engaged on the surface at all times. This eliminates the need to load a new probe, which causes time delays and the need for recalibration.
