Stroscio (physics, Duke U.) and Dutta (the Army Research Office's Director of Research and Technology Integration) focus on the study of phonons and phonon-mediated effects in structures with nanoscale dimensional confinement in one or more spatial dimensions. Pertinent to the field of optoelectronics, quantum electronics, materials science, chemistry, and biology, the phenomenon explored is important in technologies needed to fabricate nanoscale structures and devices. Geared toward practicing physicists, the theme of the work is the description of optical and acoustic phonons in such nanostructures as the superconductor superlattice, quantum wires, and carbon nanotubes.
