Resistance is one of the first concepts an electrical engineer
learns, but things get interesting at the nanoscale.
Experimentalists have found that no matter how short the resistor is,
its resistance cannot drop below a fundamental lower limit. They
also found that resistance increases in discrete steps. This brief
(15 minute) talk, a footnote to the presentation, “An Introduction to Electronics
from the Bottom Up
,” presents a simple way to understand
these important phenomena.
