Cornell Sets Record for Creating High-frequency Microresonator in Silicon
March 13, 2008
Many researchers in microelectromechanical systems (MEMS) have focused on resonators--tiny devices that vibrate at radio frequencies--to replace quartz crystals and other oscillators and can be economically integrated directly into a silicon chip. Cornell scientists are pushing the upper limits of microresonator frequency with a device that generates a 4.5 gigahertz (GHz) signal, the highest ever achieved in silicon.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
