Temperature dependence of surface plasmons on Ag(001)

Temperature dependence of surface plasmons on Ag(001) We report on high-resolution electron-energy-loss measurements of surface-plasmon losses on Ag(001) performed for crystal temperatures T in the range 100–400 K. Both the surface-plasmon frequency and linewidth are found to depend on T . The surface-plasmon frequency decreases with increasing T , nearly independently of wave vector; the linewidth increases by 7× 10 - 5 eV/K. The shift in energy is explained by the thermal expansion of the crystal, while the linewidth is influenced by the surface-plasmon–phonon interaction. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review B American Physical Society (APS)

Abstract

We report on high-resolution electron-energy-loss measurements of surface-plasmon losses on Ag(001) performed for crystal temperatures T in the range 100–400 K. Both the surface-plasmon frequency and linewidth are found to depend on T . The surface-plasmon frequency decreases with increasing T , nearly independently of wave vector; the linewidth increases by 7× 10 - 5 eV/K. The shift in energy is explained by the thermal expansion of the crystal, while the linewidth is influenced by the surface-plasmon–phonon interaction.
