Electron-Lattice Energy Exchange and Hot Electrons in Metal Island Films
Keywords:thin films, metal nanoparticles, hot electrons, electron-lattice energy exchange, computational experiment
Some aspects of the theory of hot electrons in metal island films have been considered. In particular, the influence of the electron-lattice energy exchange, which depends on the system size and on the electronic temperatures of hot electrons is analyzed in detail in the case where the system size approaches its critical value. A high sensitivity of the electronic temperature to the metal-nanoparticle size in a vicinity of this critical value is revealed. The results of computational experiments are presented which confirm the basic concepts of the theory.
