Raman Spectroscopy Group and Users Center
· The Raman spectroscopy group is focused on studies of charge and spin ordered ground states in strongly correlated electron systems. Our current aim is to investigate them with Raman spectroscopy to find general behavior for materials of different chemical origin (both organic and inorganic).
Undergraduate students are welcome to apply for internships in the Raman Users Center, please find details here and contact Dr. Natalia Drichko to apply.
