Query: Transversal flexoelectric coefficient for nanostructures at finite
  deformations from first principles   We present a novel formulation for calculating the transversal flexoelectric
coefficient of nanostructures at finite deformations from first principles.
Specifically, we introduce the concept of \emph{radial polarization} to make
the coefficient a well-defined quantity for uniform bending deformations. We
use the framework to calculate the flexoelectric coefficient for group IV
atomic monolayers using density functional theory. We find that graphene's
coefficient is significantly larger than previously reported, with a charge
transfer mechanism that differs from other members of its group.
