Emitting Diodes - Physics and Applications
(Why is Blue so important anyway?)"
Over 20 billion LEDís are produced annually, more than three for
everyone on the planet. Look around
and you see them everywhere. But
how do they work? The basic
semiconductor physics of LEDís will be discussed as well as current
applications. LEDís may some day replace incandescent lamps and are
already used in some traffic lights.
Recent advances in semiconductor manufacturing have made blue LEDís
possible. Their short wavelength opens up a new world of applications.
White light sources consisting of red blue and green LEDís are now
Please join us for light refreshments at 4:15. We hope to see you there!
