The Muscat Research Group in the Department of Chemical & Environmental Engineering at the University of Arizona works on semiconductor and metal surface chemistry, including cleaning and passivation, self-assembled monolayer formation, nanoparticle synthesis and assembly, and area selective deposition.

At left: Area selective atomic layer deposition of TiO₂ in channels made by direct writing in a self-assembled monolayer with conductive atomic force microscopy. The images of the structures are shown after each processing step. ACS Applied Nano Materials 2020, doi: 10.1021/acsanm.9b02128.
