Crossbar nanowire chips for beyond-Moore’s-law electronics

Nanowire

As transistor technology continues its march forward with smaller, faster components, we’re getting ever closer to the point at which the realities of atomic scale will put an end to Moore’s law — unless we find a way around it. A team of researchers from Harvard and non-profit research company Mitre have devised a possible solution to the problem using nanowires (NW) in tiny processors.

IBM is developing 10,000 times faster graphene chip

ibm research gfet construction ikon1

IBM builds graphene chip that’s 10,000 times faster, using standard CMOS processes. Engineers at IBM Research have built the world’s most advanced graphene-based chip, with performance that’s 10,000 times better than previous graphene ICs. The key to the breakthrough is a new manufacturing technique that allows the graphene to be deposited on the chip without it being damaged (something that has heretofore been very hard to achieve).

Scientists use DNA to shape graphene into the transistor of the future

graphene 2

Increasingly, quantum computers are predicted to be the next great leap in computational power — but in reality they are more likely to be the next next great leap. Right now we have to tailor experimental quantum chips to their particular mathematical process of interest, literally build them to solve a specific problem; today’s silicon solutions will reach the peak of their potential long before we can go buy Intel or AMD’s new plug-and-play quantum processor.

Metal–oxide–semiconductor field-effect transistor with a vacuum channel

Electrons emitted from the interface of oxide and silicon

With physical barriers limiting further increases in semiconductor electronic efficiency, scientists at the University of Pittsburgh redesigned the structure of the vacuum electronic device, allowing electrons to travel ballistically in a nanometer-scale channel without any collisions or scattering.
