Carbon-based transistors ramp up speed and memory for mobile devices
Date:7/16/2012

retain the edge.

As many as 15 years ago, technology experts realized that the problem with shrinking electronics would be the physical size of the hardware needed to make them run. The idea of a sophisticated transistor, which could do the job of both the transistor and the capacitor, was a technological dream until now.

In order to tackle this technology gap, Mentovich was inspired by the work of Israel Prize winner Prof. Avraham Nitzan of TAU's Department of Chemistry, who proved that, due to its special structure, a molecule can store both an electric charge and information at the same time. To apply this finding to transistors, Mentovich used C60 molecules, made up of 60 carbon atoms, and put them in the channels of a transistor, creating a smaller-than-silicone, high-speed transistor that could also do the job of a capacitor.

Going mobile

Mentovich believes that this technology is sorely needed in today's mobile world. 2012 was the first year in which big technology companies sold more tablets and smartphones than laptops and notebooks combined, he notes. "When this new technology is integrated into future devices, you will have much more memory on your smartphones and tablets, approaching the level of a laptop. With that kind of memory, you'll be able to run applications simultaneously, and because it is low voltage, power consumption will fall and battery life will be longer."

The next step is to find a fabrication facility with the necessary materials to manufacture the transistors. According to Mentovich, the benefit of this product is that with the right equipment, which is standard in high-tech facilities, and his breakthroughs on how to put the transistors together, these molecular memories could be manufactured anywhere. "The distance to implementation is not far," he says.
