Visible LEDs Are 50 Years Old
2012-10-09 18:40:09

Lee Rannals for redOrbit.com — Your Universe Online One technology has only just begun to be implemented into our society on a wide-scale, but it has actually been around for 50 years: the LED. The world's first visible light-emitting diode (LED) was demonstrated in 1962 by Nick Holonyak, Jr. to General Electric suits. Holonyak had predicted that the LED would replace incandescent lights, but at the time he probably didn't realize it would take 50 years to gain some traction....

U.S. scientists have constructed a light-emitting transistor that has set a record for a signal-processing modulation speed. University of Illinois researchers said they achieved a speed of 4.3 gigahertz, breaking the previous record of 1.7 gigahertz held by a light-emitting diode. Then by internally connecting the base and collector of a light-emitting transistor, they also created a new form of light-emitting diode, which modulates up to 7 gigahertz -- breaking the speed record once again....

 Researchers have constructed a light-emitting transistor that has set a new record with a signal-processing modulation speed of 4.3 gigahertz, breaking the previous record of 1.7 gigahertz held by a light-emitting diode.But, the researchers didn't stop there. By internally connecting the base and collector of a light-emitting transistor, they created a new form of light-emitting diode, which modulates at up to 7 gigahertz, breaking the speed record once again.In a pair of papers...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
