(a) An initial fcc Palladium nanowire and (b) hcp Palladium nanowire after energy minimization. (c) to lattice reorientation in Pd nanowire for an initial cross-sectional dimensions of (i.e., atomic lattice units). (d) Size dependent critical temperature for Pd nanowires, below which the nanowires do not show to reorientations.
