International Business Machines Corp. was initially optimistic about using graphene in computer chips but found electrons travel too fast in it to switch off easily, making it hard to turn current into the "ones" and "zeros" of digital code.
Labs around the world are trying to solve the problem. But for now, ' we='don' ='t see graphene replacing silicon in microprocessors," says Supratik Guha, director of physical sciences at IBM' s='research' unit,='who' says='he' remains='a' big='proponent' of='graphene.' ibm='is' a='major' graphene-patent='filer.<'>

A walk through Dr. Ferrari's labs this summer gave a window into the research. One of his associates, Felice Torrisi, showed how tape could peel graphene from a graphite clump.
