Sketch the detailed periodic potential for this model si is


Compute the bandwidth estimated by the tight-binding model using the tunneling formula. Let a=2.35A and W=10eV. What is the value of W necessary to obtain the valence bandwidth of Si, 12eV?

Sketch the detailed periodic potential for this model Si? Is this value of W reasonable and why? How does the bandwidth vary with interatomic spacing a.
