“Interaction of Graphene with Charged Particles”

ABSTRACT

The capacity of Nanotechnology to change our society and environment is limitless and is already showing effects in many segments of everyday life. Nanoscopic devices use a range of novel materials, among which graphene and other carbon allotropes play prominent roles because of their unique properties resulting from a two-dimensional lattice of carbon atoms. Being an all-surface material makes graphene extremely sensitive to the external electric fields and to the presence of charged particles in its vicinity. This property is both a blessing and a curse from a technological point of view. For example, it gives graphene a significant advantage for bio-chemical sensor applications, but the presence of indeterminate amounts of charged impurities in the materials near graphene often render measurements of graphene’s electronic and optical properties “sample dependent.” On the other hand, using a beam of fast charged particles, e.g., in an electron microscope, proved to be a powerful tool for probing the dynamic response of graphene, which is of interest for Nano-plasmonic applications. I shall adopt a broad perspective to discuss the interaction of graphene with charged particles in the context of the above applications and will review some results of recent research on those themes.

Coffee will be available in the Atrium, 2nd floor, at 1:15 p.m.

We look forward to seeing you at the Colloquium! As a courtesy to the speaker and audience, please set your cellphones to “silent” mode. Thanks!
