Hi-Frequency, Low Power Nanowire Nanoelectrochemical Field-Effect Transistors
Low power, high speed transistors (cell phone, computing devices). Disruptive semiconductor technology.
Engineers from UC San Diego have developed a novel nanoscale transistor structure that is based on both electrical transport and mechanical deformation in semiconductor nanowire materials and operates under a new mechanism of coupled nanoelectromechanical motion in order to achieve high switching speed as well as low standby power. Compared to traditional MEMS mechanical switches, a suspended field-effect channel does not rely on mechanical contacts with the gate electrode thus offer the advantage of high reliability. More specifically, this technology achieves a sub-threshold slope of zero by leveraging a high-mobility one dimensional nanowire platform. This device is poised to provide a building block for future computation.
