Theory of electron-phonon dynamics in insulating nanoparticles

摘要: We discuss the rich vibrational dynamics of nanometer-scale semiconducting and insulating crystals as probed by localized electronic impurity states, with an emphasis on nanoparticles that are only weakly coupled to their environment. Two principal regimes electron-phonon distinguished, a brief survey vibrational-mode broadening mechanisms is presented. Recent work effects mechanical interaction environment discussed.
