From
Transistor to Light-Emitting Transistor
Professor
Milton Feng, Electrical and Computer Engineering, UIUC
The
original transistor
developed in 1947 by Bardeen and Brattain was based upon the
revolutionary idea
of the "hole" playing a role as important as the electron. Over
the years, further development and
study of the physics of the transistor, including electron-hole
recombination
effects; have led to new technologies such as light emitting diodes
(LEDs),
lasers, and optoelectronics. In this
talk, we will describe how the transistor itself has become a light
emitter and
even a laser. Today, the transistor is
much more than a transistor!
