FIG. 1.

(Color online) Band structure of graphene for |λ 1| = 10 meV, α −1 = 0, EF  = 50 meV, and V 0 = 100 meV. Left part shows the spectrum on the incident side of the junction (where λ 1 = 10 meV), while the right part shows the spectrum on the transmitted side (where λ 1 = −10 meV). The solid (dotted) lines distinguish subband with opposite index l.

FIG. 2.

(Color online) Normalized conductance versus potential step height V 0 for |λ 1| as indicated, with λ 1 positive on the incidence side and negative on the transmitted side. The other parameters are as in Fig. 1.

Image of FIG. 3.
FIG. 3.

(Color online) Band structure of graphene for λ 1 = 0, α = 0.25 eV, EF  = 50 meV, and for indicated values of the potential step height V 0. Part (a) shows the spectrum on the incident (left) side of the junction, while the parts (b)–(f) show spectra on the transmitted (right) side for V 0 as indicated.

Image of FIG. 4.
FIG. 4.

(Color online) Normalized conductance versus potential step height V 0 for λ 1 = 0, EF  = 50 meV, and indicated values of the parameter α.
