"NANO-CROSSBAR: IBM grows nanotube patterns on silicon wafers"
IBM Corp. has grown catalyst-free nanotube networks on silicon carbide substrates, the company said last week. With atomic-force microscopy verifying the results, researchers at the T.J. Watson Research Center set up grids of nanotubes (in rows and columns), bringing the promise of nanotube transistors arrayed across silicon chips one step closer to reality,. IBM also announced a patent for its "cookbook" that shows how to grow the pure, catalyst-free nanotubes needed in electronics manufacturing, as opposed to the bulk nanotubes that other suppliers are offering for sale today.
