Consider an electron moving along a 1-dimensional lattice with nearest-neighbor matrix- elements V = 7 meV and a lattice constant of 2 angstroms. At room temperature the mobility is 1 cm2=Vs. What is the RMS velocity and what is the mean-free-path? Is this consistent with band or hopping transport?
