Assembly of Colloidal Crystals at Electrode Interfaces

We describe a theory for a new type of colloid behavior whereby particles deposited on a surface by electrophoresis aremanipulated to form two-dimensional crystals. Since the particles are equally charged, the clustering is opposite that expected from electrostatic considerations. Such behavior is consistentwith migrationdue to electrohydrodynamic flowsassociatedwithpolarization layers and ion ...

Femtosecond dynamics of electrons on surfaces and at interfaces.

Two-photon photoemission is a promising new technique that has been developed for the study of electron dynamics at interfaces. A femtosecond laser is used to both create an excited electronic distribution at the surface and eject the distribution for subsequent energy analysis. Time- and momentum-resolved two-photon photoemission spectra as a function of layer thickness fully determine the con...
