Research Interests
The ultimate goal of Amy Walker's research is the development of simple, robust materials for constructing complex two- and three-dimensional surfaces by manipulating interfacial chemistry. Her lab's current efforts focus on the formation and patterning of molecular thin films (self-assembled monolayers, SAMs) and the reactions of patterned films with metals, semiconductors and biomolecules, as well as the development of analytical techniques for probing the structures produced. Metal/SAM, semiconductor/SAM and biomolecule/SAM structures have applications in organic electronics, sensing, catalysis, photovoltaics and optoelectronics. Her group employs surface science techniques, in particular time-of-flight secondary ion mass spectrometry (TOF SIMS) and reflection absorption infrared spectroscopy (RAIRS) and calculations of molecular structure (density functional theory, DFT) in this work.

Keywords: Physical chemistry, analytical chemistry, surface science, nanoscience, catalysis, metal-organic thin films, new methods for the deposition of metals and other materials on organic surfaces, patterning of organic surfaces, molecular electronics, time-of-flight secondary ion mass spectrometry (TOF SIMS), mass spectrometric imaging.
