- Abstract: We study the transport properties of charge carriers in phosphorene with a
mass term through double barriers. The solutions of the energy spectrum are
obtained and the dependence of the eigenvalues on the barrier potentials and
wave vectors in the $x$-direction is numerically computed. Using the boundary
conditions together with the matrix transfer method, we determine transmission
and the conductance of our system. These two quantities are analyzed by
studying their main characteristics as a function of the physical parameters
along the armchair direction. Our results show the highly anisotropic character
of phosphorene and the no signature of Klein tunneling at normal incidence
contrary to graphene. Moreover, it is found that the transmission and
conductance display oscillatory behaviors in terms of the barrier width under
suitable conditions.
