Electronic Excitations at Metal Surfaces »

In this new work, the focus is on the dynamical response of metal electrons to several types of incident electromagnetic fields. The author, an eminent theorist, discusses Time-Dependent Local Density Approximation's importance in both elucidating electronic surface excitations and describing the ground state properties of electronic systems. Chapters detail theoretical formulations and computational procedures, covering such areas as single-particle and collective modes, spatial distribution of the induced surface charges, and local electric fields. Excitation spectra are shown for a variety of clean simple metals, noble metals, chemisorbed overlayers, charged surfaces, and small metal particles.

Discusses recent advances in describing electronic surface excitation using time-dependent local density approximation, which is preferred because it provides a rather accurate method for describing ground-state properties of electronic systems, and treats the dynamical response in a manner consistent with the one employed for the ground state. Focuses on the dynamical response of metal electrons to several types of incident electromagnetic fields. Written from a theorist's perspective but emphasizes the general physical mechanisms underlying spectroscopic observations in a manner that more practical readers might also find useful.
