Figure 3

The zero energy Green’s function in a layer with different effective mass or permittivity. The blue line is the three-dimensional Green’s function (4Πr)−1, the black line is the Green’s function (28) in a layer of different effective mass or different permittivity, and the red line is the two-dimensional logarithmic Green’s function ·G=−[γ + ln(r/2)]/4Π.
