Possible verification of tilt mismatch in asymmetric Dirac-cone systems using resonant tunneling properties

Highlights: • Tilt-mismatch effect on resonant tunneling through tilt-Dirac cone system is studied. • Tilt parameter can be determined by measuring the transport property in the system. • Tilt-mismatch can induce the pseudo-magnetic barrier without the electric potential. • This result opens the opportunity for focusing in electron-optics without magnetism. The tilt-mismatch effect on resonant tunneling through an electrical potential barrier in asymmetric tilt-Dirac cone junction is investigated. By varying barrier height, the angle-selective transmission of resonant tunneling oscillates as a function of gate voltage, and the linear phase shift due to the increase in the tilt parameter. We found that the signature of the tilt parameter can be determined by measuring the tunneling transport properties across the tilt-mismatch junction. For tilt-homogeneous junction, the tilt-induced pseudo-magnetic effect can occur only when an electric potential is applied to the system. However, the asymmetric tilt-energy dispersion systems also can mimic the pseudo-magnetic barrier structure without the electric potential. This result opens the opportunity for the tilt-Dirac cone system's magnetic focusing applications in electron-optics without magnetism.
