International Business Machines Assigned Patent for Graphene Nanoribbons, Method of Fabrication and their Use in Electronic Devices
(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service
ALEXANDRIA, Va., Feb. 2 -- International Business Machines, Armonk, N.Y., has been assigned a patent (8,361,853) developed by four co-inventors for a "graphene nanoribbons, method of fabrication and their use in electronic devices." The co-inventors are Guy Cohen, Mohegan Lake, N.Y., Christos D. Dimitrakopoulos, Baldwin Place, N.Y., Alfred Grill, White Plains, N.Y., and Robert L. Wisnieff, Ridgefield, Conn.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "The present disclosure provides a semiconductor structure including a nanoribbon-containing layer of alternating graphene nanoribbons separated by alternating insulating ribbons. The alternating graphene nanoribbons are parallel to a surface of an underlying substrate and, in some embodiments, might be oriented along crystallographic directions of the substrate. The alternating insulating ribbons may comprise hydrogenated graphene, i.e., graphane, fluorinated graphene, or fluorographene. The semiconductor structure mentioned above can be formed by selectively converting portions of an initial graphene layer into alternating insulating ribbons, while the non-converted portions of the initial graphene form the alternating graphene nanoribbons. Semiconductor devices such as, for example, field effect transistors, can be formed atop the semiconductor structure provided in the present disclosure."
The patent application was filed on Oct. 12, 2010 (12/902,620). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8,361,853.PN.&OS=PN/8,361,853&RS=PN/8,361,853
