  We investigate the effects of a perpendicular electric field applied to
multilayer phosphorene nanoribbons with zigzag and armchair edges. Within the
context of the tight-binding model, we explore the electronic properties of
these systems giving emphasis to the appearance of Dirac-like spectra, a
transition that occurs when the gate density associated with the applied
displacement field is greater than the critical value $n_c$. We show that the
confinement properties and the screening effects in such systems play an
important role on the determination of $n_c$, suggesting a scheme to determine
the thickness, width and edge orientation of multilayered phosphorene
nanoribbons. We also explore how this transition affects the electronic
transport properties of such systems.
