Quenching effect of oscillating potential on anisotropic resonant transmission through a phosphorene electrostatic barrier

Abstract The anisotropy in resonant tunneling transport through an electrostatic barrier monolayer black phosphorus either presence or absence of oscillating potential is studied. Non-perturbative Floquet theory applied to solve the time dependent problem and results obtained are discussed thoroughly. resonance spectra field free transmission Lorentzian nature although width for along zigzag (Г–Y) direction too thinner than that armchair (Г–X) one. Resonant suppressed both cases by application produces small oscillations around energy particularly at low frequency range. Sharp asymmetric Fano resonances noted spectrum while a distinct line shape higher potential. Even after angular average, conductance Г–X retains characteristic features could be observed experimentally. present supposed suggest phosphorene used successfully as switching devices nano detectors.
