Abstract

The scanning electron microscope (SEM) provides an excellent environment for nanophotonics research, as the electron beam can be used not only for imaging, but also for nanoscale excitation and probing of samples. This talk will review recent studies of optical memory and switching functionalities in gallium nanoparticles performed in an SEM environment.Most recently, it has been found that the phase state of bistable gallium nanoparticles, controlled by optical or electron beam excitations, can be identified via measurements of their cathodoluminescent emission, thus offering an innovative conceptual basis for the development of high density non-volatile phase-change memories. Changes of up to 20% in visible emission intensity are observed following low-fluence optical or electron beam induced phase switching in a monolayer of 60 nm particles.
