IBM Corp. and Georgia Tech announced Tuesday they have built a transistor that runs about 100 times faster than current chips, a development that could lead to advances in cell phones, radar technology and space exploration.
Although the new chip is far from commercial availability, the latest development is an important step in showing the electronics industry the speeds that silicon-based chips could reach, researchers say.
After cooling down a silicon-germanium chip to approximately minus 268 degrees Celsius, researchers from IBM and Georgia Tech were able to clock the transistor at 500 gigahertz, versus a speed of about 350 gigahertz at room temperature.
