Cherie R Kagan Research Group

The Kagan group’s research is focused on studying the chemical and physical properties of nanostructured materials and in integrating materials with optical, electrical, magnetic, mechanical, and thermal properties for (multi-)functional devices. We combine the flexibility of chemistry and bottom-up assembly with top-down fabrication techniques to design materials and devices. We explore the properties of materials and measure the characteristics of devices using spatially- and temporally-resolved optical spectroscopies, AC and DC electrical techniques, electrochemistry, scanning probe and electron microscopies, and analytical measurements.
