Abstract

Chiral tunneling oscillations are investigated by modulations of a double potential barrier based on Weyl semimetals . Analytical results are directly derived from transfer matrix constituted by the parametric controls, which range to the incoming energy, incident angle, width and strength of the potential barriers. Referring to the analytical analysis and numerical simulations, the transmission and conductance resonances effected by the double potential barrier can be clearly obtained and understood. Specially, modulations of the chiral tunneling show that resonant oscillations emerge in serial high incident energies, and platforms of low transmission probability come into existence due to propagations of the imaginary wave vectors.
