Explanation:

DEFINITION, DESCRIPTION AND DERIVATION OF EFFECTIVE MASS OF ELECTRON,effective mass is that mass which an electron seems to have when it is present in the periodic potential in a lattice crystal. NATURE the graph between the energy and the propagation constant (k) is in the parabolic form.

Effective mass for density of states calculations

where Mc is the number of equivalent band minima. For silicon one obtains: me,dos* = (ml mt mt)1/3 = (6)2/3 (0.89 x 0.19 x 0.19)1/3 m0 = 1.08 m0.8

For electrons or electron holes in a solid, the effective mass is usually stated in units of the rest mass of an electron, me (9.11×10−31 kg).

hope this help uhh
