Query: Proximity induced Colossal Conductivity Modulation in Phosphorene   Phosphorene is a promising single elemental two-dimensional layered
semiconductor with huge potential for future nanoelectronics and spintronics
applications. In this work, we investigated the effect of an organic molecule
(benzene) in the close proximity of a Phosphorene nanoribbon. Our extensive
calculations reveal that the semiconducting nature of Phosphorene stays
unaffected as a result of the molecular adsorption while the transport
properties go through drastic changes. Under the influence of dopant atoms and
external strain, colossal changes in the conductivity is observed with a
maximum enhancement > 1500% which has not been observed earlier. This effect is
pretty robust against the (i) variation of system size, (ii) type, location and
concentration of dopants and (iii) nature and magnitude of the external strain.
Furthermore, we demonstrated how a gate voltage can be used to fine tune the
enhanced conductivity response in a Field-effect transistor (FET) structure.
Our results provide new direction for Phosphorene based nanoelectronics in
applications like sensing, switching where a higher level of conduction can
offer better resolution, higher ON/OFF ratio and superior energy efficiency.
