2DCHEX: Antenna for enhanced electron-matter interactions

Research output: Contribution to conference without publisher/journal › Poster › Communication

Abstract

Development of a novel type of antenna for enhancing the electron interaction with transition metal dichalcogenide (TMD) monolayers. As monolayers are atomically thin, the exposed volume to electron beam at normal incidence is extremely small, which severely limits the electron-monolayer interaction. Therefore, a nano electron antenna – a gold crystalline nanodisk – redirects incoming electrons along the monolayer plane, allowing for in-plane excitations. Remarkably, such an excitation results in the highest observable to date photon bunching.
