Dear all,

Have you any idea about the electron speed at 0K when the electron is free?

In the free electron model of solids, I belive that the fermi velocity is approx 10^6 m/s

Of course, this depends on the electron density in the solid (and is true, independent of the model).

A truly free electron, however, can have any velocity (v<c) you give it. And whose temperature are you (pang) talking about?
