The research in our laboratory is focused on understanding and controlling surface and interfacial chemistry and applying this knowledge to a range of problems in semiconductor processing, micro- and nanoelectronics, nanotechnology, and sustainable and renewable energy. The role of interfaces becomes increasingly important as system dimensions are scaled downward. Much of our research aims to develop a molecular-level understanding in these systems, and hence the group uses a variety of molecular probes. Systems currently under study in our group include organic functionalization of semiconductor surfaces, mechanisms and control of atomic layer deposition, molecular layer deposition, area selective deposition processes, nanoscale materials for light absorption, interface engineering in photovoltaics, and catalyst and electrocatalyst synthesis and characterization.
