Consider an electron in the conduction band of GaAs in an infinite potential well of width 20nm. (a) Calculate the energies in (meV) associated with the transitions between the five lowest levels (E,, E,, Eg, E4. Es). Draw a diagram for the possible transitions (see Fig. 2.13 from our main reference Levi). Assume that the effective mass of GaAs is m² = 0.067m. (m. = electron mass); (b) Write the associated wavefunction for each of these five lowest level states
