Why do we need to know about Nano-electronic
“materials” details? - A Case study of the evolution of the Transistor
Common Statement: First Transistor was invented by Shockley,
Brattain and Bardeen on December 23, 1947 at 5 PM - Wrong!
The first patent for the field-effect transistor principle was filed in
p p p
Canada by Austrian-Hungarian physicist Julius Edgar Lilienfeld on
October 22, 1925




The level of understanding you gained about transistors in ECE 3040 is 60 years old!!!!
