“…The transcendental equation [Eq. (15)] provides four types of solutions for the propagation constant k 0x due to the ± signs for k 1z and k 0z [50]. The branch leading to perfect absorption corresponds to both k 1z < 0 and k 0z < 0, yielding fast-wave (k 0x /k 0 < 1), nonradiative (k 0x ∈ ) modes that represent a coherent superposition of waves that propagate without loss along the BP surface [43].…”

“…The latter bonding results in a layered configuration consisting of two-dimensional phosphorus sheets. These weakly interacting two-dimensional layers provide a unique opportunity to create different orderings of two-dimensional layers with extremely low-cost and simple operations, including displacement and twist [5][6][7][8][9][10][11][12][13][14][15][16][17]. The ordering and number of layers, as well as their deformation, can effectively control the electronic properties of BP-based devices.…”

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