If there are 3 quantum wells separated by the same distance in a 1-D array with wavefunction ψ1 , ψ2 , and ψ3 for these three quantum wells respectively. The electrons only acts on the neighboring electrons with perturbation energy H’ = -|ΔE|. If the original eigen energy of ψ1 , ψ2 , or ψ3 is E1, try to use degenerate perturbation theory to calculate and sketch the new eigen energies for this array with 3 quantum wells.

2. 2D Density of States (~Kasap 4.9) Kasap Section 4.5 (in 4th Ed.) derives an expression for the density of states for electrons in a 3D infinite potential well (3D Sommerfeld box). This derivation is similar to the one we did in class. a. Following the approaches used in the 3D derivations, consider an electron confined to a 2D infinite potential well and derive an expression for the 2D density of states, g2D, which is the number of states per...
