After this lecture you will be able to:
- - formulate equations of motion describing electrons and phonons in 1D.
+ - formulate equations of motion for electrons and phonons in 1D.
- solve these equations to arrive at the corresponding dispersion relations.
- - derive the group velocity, effective mass, and density of states from a dispersion relation.
