Carbon Diamond Technology

Professors W.P. Kang and Jimmy L. Davidson (Electrical Engineering) are finding ways to leverage diamond and other carbon structures for use in integrated circuits, power switches, energy-conversion devices, biosensors, flat-panel displays, and even military uniforms. Silicon stops working at about 200 degrees Fahrenheit, but diamond is still going strong when the mercury is approaching 1,000 degrees. 

Davidson and Kang are developing nanocarbon and nanodiamond materials for advanced electronics and energy conversion.  They are taking an ‘old’ technology (vacuum tubes) and are shrinking it to work with diamond such that fast and powerful transistors and equivalent integrated circuits are created that perform in extreme environments at lower power.   

"Imagine a laptop without a hot spot, no fan, and stays powered for weeks instead of hours," says Davidson about the diamond nanotechnology devices.  "Also, we can use the nanodiamond emitters to convert heat directly to electricity much more efficiently than power plants, significantly reducing oil and coal consumption and pollution."
