Mesoscale Materials Laboratory

The Mesoscale Materials Laboratory, under the direction of Dr. Jonathan Spanier, investigates the electronic and functional properties of thin-film and nanoscale materials and devices. The group is actively involved in designing, preparing, and characterizing new materials, their surfaces, and their interfaces with other materials. In their work, they seek to address challenges relating to scaling and performance of transistors, and are working to advance photovoltaic science and technology via new polar oxide materials, including their preparation, and laser spectroscopic and scanned proximal probe characterizations. These investigations are aided by studies of how functional and multi-functional properties can be tailored and improved in nanostructured materials.
