Unformatted text preview: following problem using MATLAB: Assume that the potential well width is 200 A. V(x)= 4.0 eV to the left of the well V(x)= 3.5 eV to the right of the well V(x)=0 inside the well (a) Submit the printout of the script you used. (b) What are the energies of the first five bound levels? Do they follow E n ~ n 2 rule for infinite well ? Check by setting the left and right potential to 20 eV each. Submit a plot of E n vs. n for both cases. (c) For both cases, plot the square of the wavefunctions (probability of finding an electron at location x) for the first five levels. • Save the scripts, we shall use them to solve other problems. • Later you will see the this structure is relevant to modern MOSFETs....
