Query: Enhanced Eshelby Twist on Thin Wurtzite InP Nanowires and Measurement of
  Local Crystal Rotation   We have performed a detailed study of the lattice distortions of InP wurtzite
nanowires containing an axial screw dislocation. Eshelby predicted that this
kind of system should show a crystal rotation due to the dislocation induced
torque. We have measured the twisting rate and the dislocation Burgers vector
on individual wires, revealing that nanowires with a 10-nm radius have a twist
up to 100% larger than estimated from elasticity theory. The strain induced by
the deformation has a Mexican-hat-like geometry, which may create a tube-like
potential well for carriers.
