Will III-V Materials Beat Carbon-based Nanotubes and Graphene?

NO RATINGS
IBM has been working long and hard to define the next generation of semiconductors--such as carbon based nanotube- and graphene-transistors. Nanowires made from III-V materials like GaAs, InGaAs and InAs however, may turn out to be easier to integrate into the CMOS design flow than carbon-based materials. What do you think?

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
