New computer switches handle heat that renders transistors useless
Date:10/7/2010

leakage and no loss of power in testing at 500 degrees Celsius.

A pair of switches were used to make an inverter, which was able to switch on and off 500,000 times per second, performing computation each cycle. The switches, however, began to break down after 2 billion cycles and in a manner the researchers do not yet fully understand.

"We made a building block," Bhunia said. "Next, we're trying to make memory. If we can combine them, we can build a computer."

He and the others are confident that with improvements in production, they can build more durable switches that can cycle faster.

Whether they can reach the point of competing with faster transistors for office and home and even supercomputing, remains to be seen. The researchers point out that with the ability to handle much higher heat, the need for costly and space-consuming cooling systems would be eliminated.
