  • Patent number: 8263002
    Abstract: The nanofabrication of a hydrogen gas nanosensor device from single straight and branched, tripod shaped ZnO nanorods using in-situ lift-out technique, performed in the chamber of a focused ion beam (FIB) system is disclosed. Self-assembled ZnO branched nanorods have been grown by a cost-effective and fast synthesis route using an aqueous solution deposition method and rapid thermal processing. The properties of the ZnO nanorod structures were analyzed by X-ray diffraction, scanning electron microscopy, energy dispersion X-ray spectroscopy, transmission electron microscopy and micro-Raman spectroscopy. High quality ZnO nanorods were obtained with a 90% success rate for building nanodevices. The fabricated nanosensor can gauge 150 ppm hydrogen gas in the air at room temperature. The nanosensor has selectivity for other gases such as oxygen, methane, carbon monoxide and liquid propane gas. The ZnO nanorod sensors of the present invention also operate at low power of less than 5 microwatts.

  • Patent number: 7422667
    Abstract: Carbon nanoparticles including both nanofilaments and nanotubes produced by an electrochemical deposition method from organic solutions at room temperature, in which the formation and growth of carbon nanoparticles are stimulated by the catalyst, such as iron and nickel. It has been found that the electrochemical deposition conditions have a strong influence on the growth phenomenon of the carbon nanotubes. Scanning electron microscope (SEM) and transmitting electron microscope (TEM) characterizations show that the diameter of nanotubes is of the order of approximately 100 nm, and the length of filaments can be up to approximately 50 ?m, depending on the size of catalyst particles.

  • Patent number: 7009487
    Abstract: The method for the fabrication of nano scale temperature sensors and nano scale heaters using focused ion beam (FIB) techniques. The process used to deposit metal nano strips to form a sensor is ion beam assisted chemical vapor deposition (CVD). The FIB Ga+ ion beam can be used to decompose W(CO)6 molecules to deposit a tungsten nano-strip on a suitable substrate. The same substrate can also be used for Pt nano-strip deposition. The precursors for the Pt can be trimethyl platinum (CH3)3Pt in the present case. Because of the Ga+ beam used in the deposition, both Pt and W nano-strips can contain a certain percentage of Ga impurities, which we denoted as Pt(Ga) and W(Ga) respectively. Our characterization of the response of this Pt(Ga)/W(Ga) nano scale junction indicates it has a temperature coefficient of approximately 5.4 mV/° C. This is a factor of approximately 130 larger than the conventional K-type thermocouples.
