- Summary
- Imagine to have a perfect conductor, i.e. no impurities and no thermal motion (0K)

According to the semiclassical approximation, in response to a constant electric field I would get a periodic motion of the electron, like this:

The sinusoidal type function is the velocity, while the function that goes to infinity is the effective mass. Thus I was wondering, since ##v## also gets negative values, does it means that an electron oscillates back and forth ?

Thanks,

Ric
