Description:
Author(s): Christoph Kloeffel, Mircea Trif, and Daniel Loss We study theoretically the low-energy phonons and the static strain in cylindrical core/shell nanowires (NWs). Assuming pseudomorphic growth, isotropic media, and a force-free wire surface, we derive algebraic expressions for the dispersion relations, the displacement fields, and the stress and stra... [Phys.
