Fig. Q2(a) shows the full width at half maximum (FWHM) of the electron wavefunction in the first quantised state as a function of the well width L for a potential barrier height of 250 meV in a quantum well. Explain briefly why FWHM goes through a minimum value at L = 2.5 nm and then increases again as L 0
