Lecture 2 Applications of the free electron gas model
... metals, such as Al, have a positive RH value. Therefore it would appear that in some materials electrons are positively charged, contrary to what we expect. In order to resolve this difficulty we need to develop a better theory of electrons in metals. This will be our goal for the next few lectures. ...
