Band gap of bulk(thatis, large size, macroscopic crystal)silicon is 1.14 ev. a quantum dotcan be modelled as an infinite square well in 3 dimensions, and the band gap is differentfor a quantum dot. consider a silicon particlethat is a cubeof size 4nm. calculatethe band gap for this particle, which isthe energy difference between the lowest energy level of the electron in the conduction band and the highest energy level of the hole in the valence band.
