Electron speed at 0K

    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?
