Figure 6

Ground and first excited states. Ground and first excited state energies of the electron (colored lines) as functions of the (a) inner and (b) outer radii of the QR for L=20 nm, P=0, and F=0. The impurity is placed at z i  = 0 and ρ i  =  (R1 + R2)/2. The insets show the corresponding energy difference between the 2s and 1s states.
