2D-SURFACE PHONONS IN HIGH-RESOLUTION ELECTRON-ENERGY-LOSS SPECTRA OF METALLIC OXIDES
Surface phonon features in high-resolution electron-energy-loss (HREEL) spectra of the metallic tungsten bronze oxide Na0.7WO3 are much weaker than for insulating WO3. Models based on the bulk dielectric function ε{lunate}(ω) are unable to rationalise these spectra, but a simple two-layer model invo...
