Overview
The ultimate goal of Dr. Amy Walker’s research is the development of simple, robust materials for constructing complex two- and three-dimensional surfaces by manipulating interfacial chemistry. Metal/SAM, semiconductor/SAM and biomolecule/SAM structures have applications in organic electronics, sensing, catalysis, photovoltaics and optoelectronics. Walker’s group also develops analytical techniques to probe the structures produced.
The Walker 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 or DFT) in this work. ToF-SIMS is a unique widely applicable technique that provides detailed information about the chemical composition of surfaces with submicron lateral resolution and is used in areas from biological systems to materials science.
Research Interests
- New methods for constructing metallized organic surfaces
