Resonant tunneling diode oscillators for terahertz-wave detection

A semiconductor device that is promising for both generating and detecting terahertz radiation has been demonstrated by physicists at RIKEN. This may aid the development of high-performance integrated solutions for terahertz ...

Low-temperature plasma device may lead to more efficient engines

Low-temperature plasmas offer promise for applications in medicine, water purification, agriculture, pollutant removal, nanomaterial synthesis and more. Yet making these plasmas by conventional methods takes several thousand ...

Faster LEDs for wireless communications from invisible light

Researchers have solved a major problem for optical wireless communications—the process by which light carries information between cell phones and other devices. Light-emitting diodes (LEDs) pulse their light in a coded ...
