Visible LEDs Are 50 Years Old

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
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
