Faraday Discussion 117
EXCITED STATES AT SURFACES
The University of Nottingham, UK, 4-6 September 2000
Many interfacial processes implicitly involve the creation and decay of
excited states. This Discussion will highlight their role in experimental
and theoretical surface science. We shall consider a wide range of
phenomena including surface spectroscopies and reactions to arrive at a
deeper understanding of the main issues by explicitly including a
description of transient states.
Excited electronic states play a pivotal role in measurements in both the
energy and time domain. Hole decay in optical spectroscopies has a long
history but the advent of newer probes (e.g. multiphoton photoelectron
emission) with improved resolution suggests that we are now in a position
to test some of the long-standing paradigms. Many interesting resonance
phenomena have been observed in electron energy loss spectroscopy from
adsorbates and again new theoretical descriptions are required. The
explosion of interest in scanning probe microscopies has focussed attention
on the behaviour of processes in real space. The injection of electrons
into molecular states at low energies gives rise to diffusion and complex
restructuring in adsorbate layers. Elementary models have been proposed
within the framework of Frank-Condon dynamics but with the emergence of
high quality (albeit ground-state) electronic structure calculations is it
possible to formulate excited state scenarios? The Discussion will also
focuss on excited molecular states interacting with surfaces. The dynamics
of a state-prepared molecule when it nears a surface is amazingly
complicated with a wide range of final states possible (dissociation,
scattering etc.). The interaction with the surface atomic and electronic
degrees of freedom gives rise to transient excited states that dissipate
energy and information. Are we yet in a position to arrive at a consistent
theoretical description capable of including these effects?
Experimental and theoretical contributions relating to the above areas or
to any other, unmentioned, aspects of excited states at surfaces will be
most welcome.
Papers should be concerned with NEW, UNPUBLISHED WORK and contributions of
both an experimental and theoretical nature are welcome. Titles and
abstracts, of about 300 words should be submitted no later than FRIDAY 3
SEPTEMBER 1999 to Professor S Holloway, Surface Science Research Centre,
