Patent number: 8263002Abstract: 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.Type: GrantFiled: May 13, 2009Date of Patent: September 11, 2012Assignee: University of Central Florida Research Foundation, Inc.Inventors: Lee Chow, Oleg Lupan, Guangyu Chai

Patent number: 7009487Abstract: 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.Type: GrantFiled: January 23, 2004Date of Patent: March 7, 2006Assignee: University of Central Florida Research Foundation, Inc.Inventors: Lee Chow, Dan Zhou, Fred Stevie
