Electrons in weak periodic potential
... Conversely energy eigenvalues of the electrons moving through the empty lattice for a given k values in the reduced zone scheme can be got from the free-electron dispersion curve by finding the equivalent k values inside the first Brillouin zone for each wave number outside of it, and then shifting ...

Uniform Electric Fields and Potential Difference
... • All this talk about work makes me think about energy...how do we describe energy when talking about electricity? • In electricity, we talk about energy per unit of charge. Just as we described E-fields as the amount of force per unit of charge, we can describe the Potential Difference as the ener ...
