  A multi-scale approach for the theoretical description of deformed
phosphorene is presented. This approach combines a valence-force model to
relate macroscopic strain to microscopic displacements of atoms and a
tight-binding model with distance-dependent hopping parameters to obtain
electronic properties. The resulting self-consistent electromechanical model is
suitable for large-scale modeling of phosphorene devices. We demonstrate this
for the case of an inhomogeneously deformed phosphorene drum, which may be used
as an exciton funnel.
