SUMMARY

The discussion centers on the speed of electrons at absolute zero (0K) in the context of solid-state physics. Patrick states that in the free electron model, the Fermi velocity is approximately 10^6 m/s, which is influenced by electron density. Additionally, it is clarified that a truly free electron can possess any velocity below the speed of light (v PREREQUISITES

  • Understanding of solid-state physics concepts
  • Familiarity with the free electron model
  • Knowledge of Fermi velocity and its implications
  • Basic principles of thermodynamics, particularly absolute zero
NEXT STEPS
  • Research the free electron model in solid-state physics
  • Study the concept of Fermi velocity and its calculations
  • Explore the behavior of electrons at different temperatures
  • Investigate the implications of electron density on conductivity
USEFUL FOR

Physicists, materials scientists, and students studying solid-state physics or thermodynamics will benefit from this discussion.

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 believe 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?
