Transmittance as function of the energy for BGDBs. (a) Transmission spectra for different angles of incidence: 1° (solid-black line), 3° (dashed-red line), 5° (dotted-blue line) and 15° (dash-dotted-green line). The widths of barriers-well and the heights of the barriers considered were dB = dW = 6 nm and V 0 = 50 meV, respectively. (b) Evolution of the transmittance for different widths of barriers-well dB = dW \(=:\) 3 nm (solid-black line), 6 nm (dashed-red line), 9 nm (dotted-blue line) and 10 nm (dash-dotted-green line). The angle of incidence and the height of the barriers in this case are θ = 3° and V 0 = 50 meV, respectively. (c) Similar to (b) but here the widths considered are 3 nm (solid-black line), 6 nm (dashed-red line), 7 nm (dotted-blue line) and 9 nm (dash-dotted-green line). In this case the height of the barriers has been increased to V 0 = 100 meV.
