Current methods of generating terahertz radiation involve lasers, thermionic valves and special circuits cooled near absolute zero, often in room-sized apparatuses costing thousands of dollars.
Cornell researchers with Ehsan Afshari, assistant professor of electrical and computer engineering, have developed a new method using the familiar and inexpensive CMOS chip technology, generating power levels high enough for some medical applications.
