Scaled effective model. (a) Scaled effective potential. (b) Effective current transmission at u = 0.1, vD = 0.5, and vG = 0 ( = 0.504 and m = 0.992). The considered characteristic lengths are l = 4 (red, weak barrier, β = 15.87) and l = 25 (green, strong barrier, β = 619.8). The ideal limit (Equation 19) in blue line.
