Question

1) For a semiconductor E vs kx near the band edge Ec is given by E=Ec +(h2/16m0)*kx2    Determine the effective mass of electrons in the conduction band. Here m0 is the mass of a free electron. 2) E vs. kx for electrons near the valence band edge Ev can be approximated by
E=Ev-0.1(h2/4m0)*kx2 Find the effective mass of holes in this material. 1) For a semiconductor E vs kx near the band edge Ec is given by E=Ec +(h2/16m0)*kx2    Determine the effective mass of electrons in the conduction band.
