Plasmonics: Fundamentals and Applications

The surface science of titanium dioxide

Self-assembly is the autonomous organization of components into patterns or structures without human intervention. Self-assembling processes are common throughout nature and technology. They involve components from the molecular (crystals) to the planetary (weather systems) scale and many different kinds of interactions. The concept of self-assembly is used increasingly in many disciplines, with a different flavor and emphasis in each.

Self-assembly at all scales.

Recent developments have greatly improved the sensitivity of optical sensors based on metal nanoparticle arrays and single nanoparticles. We introduce the localized surface plasmon resonance (LSPR) sensor and describe how its exquisite sensitivity to size, shape and environment can be harnessed to detect molecular binding events and changes in molecular conformation. We then describe recent progress in three areas representing the most significant challenges: pushing sensitivity towards the single-molecule detection limit, combining LSPR with complementary molecular identification techniques such as surface-enhanced Raman spectroscopy, and practical development of sensors and instrumentation for routine use and high-throughput detection. This review highlights several exceptionally promising research directions and discusses how diverse applications of plasmonic nanoparticles can be integrated in the near future.

For UV photoinduced desorption of ammonia and deuterated ammonia from Cu (1 1 1) at hv = 6.4 eV, strong isotope effects are found, which increase from σ NH 3 σ ND 3 = 1.9 ± 0.5 to 4.1 ± 1.2 when the coverage is decreased from 0.14 to 0.02 monolayer (ML), respectively. The coverage dependence of the isotope effect is attributed to a variation of the desorption probability with adsorbate binding energy. The magnitude of the isotope effect suggests that nuclear motion along an intramolecular coordinate during a short-lived electronic excitation facilitates desorption. We propose that after deexcitation to the electronic ground state potential energy surface, efficient coupling of the highly vibrational excited inversion mode with the molecule-surface coordinate leads to desorptio. Trajectory calculations performed on a two-dimensional model potential energy surface predict that desorption occurs rapidly within a few vibrational periods of the umbrella mode (Tvib ∼ 35 fs) — with comparable energy release into the translational and vibrational degrees of freedom.

Methods and Applications of UV Photoelectron Microscopy in Heterogeneous Catalysis

A multitude of methods from surface physics in combination with molecular beam and laser spectroscopic techniques provides detailed insight into the various aspects of the dynamics of interactions between molecules and surfaces, reaching from macroscopic kinetics over phenomena of spatiotemporal self-organisation to the microscopic elementary process. The present state of our knowledge is illustrated by means of selected examples, concerning mainly single crystal surfaces of metals.
