Research Objectives

I examine two-dimensional, atomically thin chalcogenide layered structures. Because these materials are placed under spatial confinement, they tend to exhibit novel, yet tunable phenomena. Through the use of a variety of advanced microscopy and spectroscopy techniques, I have examined the impact various interfaces in these materials have on electronic, optical, and magnetic properties. This work has been done in an effort to pave the way for these materials to be used in next-generation electronic devices.
