Lloyd’s group specializes in surface physics at the nanometer-scale in condensed phase systems. The overarching goal is to understand the electronic and the optoelectronic characteristics of individual molecules and functional nanometer-scale assemblies. Insight into critical technological problems, such as molecular-scale electronics, molecular light-emitting diodes, light harvesting systems, and the environmental stability of surfaces relies on understanding fundamental chemical and physical processes at the nanometer scale. The experimental approach is to combine the molecular-scale resolution of scanning probe techniques, such as scanning tunneling microscopy and atomic force microscopy, with optical spectroscopy. The group is also interested in developing novel scanning probe techniques. The experimental tools are well suited for addressing several technological challenges encountered in designing and realizing quantum hybrid systems such as those relying on surface plasmons.
