Research Abstract |
We studied vibrational modes in wire-type phononic crystals, i.e., nanowire superlattices, based on the xyz algorism. We numerically calculated the phonon dispersion relations and corresponding displacement fields for several nanowire superlattices consisting of anisotropic materials. For a circular cross-section GaN/AlN nanowire superlattice, we determined a set of parameters which gives complete phononic bandgaps.
