It is surprising that any good at all comes out of an approach in terms of external
forces alone , but we shall see that the effective mass is a most useful quantity .
From ( 11.37 ) we have ( 11.12 ) dı , dt = h- ? d ? E / dkdt = h - ' ( d'E / ak :-) ( dk / dt

Although k is increased by Ak by the applied electric field , the consequent Bragg
reflections result in an overall decrease in the momentum of the electron , so that
the effective mass may be described as being negative . As we proceed from E ...
