DESCRIPTION:Dr. Agustin E. Schiffrin\, Quantum Matter Institute\, Universi
 ty of British Columbia\, Vancouver\, British Columbia\, Canada\nControllin
 g the nanoscale structural and electronic properties of surfaces yields pr
 omise for the development of functional nano-patterned solid interfaces. I
 n particular\, low-dimensional supramolecular nanoarchitectures with well-
 defined morphology and electronic structure can exhibit optoelectronic res
 ponses which can be exploited in light-harvesting and photocatalytic appli
 cations. In order to ensure a hierarchical transfer of function from the n
 ano- to the macro-scale\, electronic characterization at the single molecu
 le level is essential.\nIn the first part of my talk\, I will show how pro
 tocols of supramolecular chemistry on a surface can be applied to tailor t
 he structural and electronic properties of a solid interface. I will focus
  on self-assembled biomolecular and metal-organic nano-assemblies on noble
  metal surfaces. These systems are characterized at the atomic scale by me
 ans of low-temperature scanning tunneling microscopy and spectroscopy\, an
 d complementary photoelectron spectroscopy.\nOptoelectronic functionality 
 of a surface is given by its out-of-equilibrium electron dynamics resultin
 g from an external optical excitation. In a second part of my talk\, I wil
 l demonstrate the sub-femtosecond generation and control of electronic sig
 nals at a solid interface with the electric field of light.\nI will finall
 y address my current and future research perspectives\, which deal with th
 e bottomup design of photoactive supramolecular nanostructures on a surfac
 e\, as well as with the realtime characterization of ultrafast photo-induc
 ed electron dynamics in such nanosystems.
