Question

Calculate how much increase (in eV) of the conduction band edge would be resulted for the 10th subband, if you have created a quantum well (i.e., with 1D subband and 2D dispersion relation) by size quantization in the z-direction (thickness direction), resulting in a 5 nm-thick channel. In the parabolic dispersion (E-k) relation we learned in class, mc (conduction band effective mass) should be used for electron’s mass. Assume your channel is GaAs (mc for GaAs is 0.07mo, where mo is the free electron mass of 9.11 x 10-31 kg). Show your work for the full credit.

Irn the parabolic dispersion (E-k) relation we learned in class, mc (conduction band effective mass) should be used for electron's mass. Assume your channel is GaAs (mc for GaAs is 0.07me, where mo is the free electron mass of 9.11 x 1031 kg). Show your work for the full credit.
