Using ( 11 . 41 ) for dk / dt , we have ( 11 . 43 ) dvo _ d ' E eɛ at - dk2 h2 It
appears on comparison with the classical equation dv / dt = eɛ / m that hp / ( d ' E
/ dk ? ) plays the role of a mass , and we call this quantity the effective mass m * : (

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 ...
