a TER of the FTJ 1′–3′ as a function of E. The curves of insets show the corresponding tunneling potential profiles, blue for polarization pointing to the left and red for polarization pointing to the right. The arrows indicate the directions of the polarization. b Conductance G per lateral area of FTJs as a function of energy E for polarization pointing right (solid) and left (dotted). The Fermi energy is at zero. Green, orange, black lines represent FTJ 1′–3′, respectively.
