2. DENSITY OF STATES Calculate and plot the density of states as a function of energy.r in the conduction band of a CraAszlGaAs quantum well for the rst three bound states located at 25. 100. and 225 meV above the conduction band edge The electron effective mass of GaAs in the conduction band is m* = 0.06? mg. Plot the density of states for bulk GaAs on the same axis as the quantum well. Please create your plot using your preferred plotting software and attach the code
