Binding energy (top) and electron average radius (bottom) as a function of the core radius, considering the confining shell width as W = 50 Å (black squares), 75 Å (red circles), and 100 Å (blue triangles). The arrows indicate the points and 270 Å, whose wave functions are illustrated in Figs. 2(a) and 2(b) , respectively.
Electron effective potential (black solid), considering (a) and 270 Å (b), along with their respective electron (blue solid) and hole (red dashed) wave functions.
Exciton transition energy (top) and ground state electron average radius (bottom) as a function of the magnetic field intensity, for W = 100 Å and . We consider two values for the hole angular momentum index, (black solid) and (red dashed), and several values forthe electron angular momentum index le . The wave functions for the and states at the two values of magnetic fields pointed by the arrows are illustrated in Fig. 4 . Notice the vertical axis of the bottom panel has a break between 92.8 Å and 520 Å, in order to improve the visualization of the curve.
Electron effective potentials (black), along with their respective electron (blue) and hole (red) wave functions, for the two different values of magnetic field pointed in Fig. 3 : (a) B = 0.4 T and (b) B = 0.65 T. The insets show the exciton transition energy as a function of the variational parameter η for each value of magnetic field.
