Phonons on Cu(001) surface covered by submonolayer alkali metals.

J Phys Condens Matter

Institute of Strength Physics and Materials Science, pr. Academicheskii 2/4, 634055, Tomsk, Russia. Tomsk State University, 634050, Tomsk, Russia.

Published: March 2019

We present a theoretical investigation of the structural and vibrational properties of ordered 2D phases formed by the Li, Na and K atoms on the Cu[Formula: see text] surface. The lattice relaxation, phonon dispersions and polarization of vibrational modes as well as the local density of states are calculated using the embedded-atom method. The obtained structural parameters and vibrational frequencies are in close agreement with available experimental results.
