International Online Workshop

Electrons, Photons and Plasmons 2021

March 10-12, 2021

Objectives and format

Electron-energy loss spectroscopy (EELS) and scanning near-field optical microscopy (SNOM) are powerful and rapidly developing techniques to study various spatially and temporally textured excitations in solids and molecules, such as plasmons. While they ultimately yield similar information on such modes using respectively electrons and photons as probing particles, the mechanism through which these techniques do so can be radically different. The goal of this workshop is to bring together EELS and SNOM experts in order to exchange on the recent progress in these methods and to discuss their possible symbiosis. The topics will cover fundamental research, instrumentation, modelling and applications.

The program includes invited talks and contributed posters. The maximum number of participants is 300 persons. Young scientists and female participants are highly welcome.

The program extends over three days from 15:00 to 20:00 (CET). Every day there will be 1  tutorial/research talk (40 min), followed by 6 research talks (25 min), a discussion session and a poster session.

The detailed program can be downloaded here.


Every poster presenter will be given a personal virtual room, which other participants can visit during any of the three poster sessions. The posters do not need to be of traditional (A0) size. Instead, we advise the presenters to prepare a short oral presentation (up to 7 slides), which can be shown several times during the session of 45 minutes.

The preliminary list of posters can be downloaded here.



All participants are requested to register and indicate whether they wish to present a poster, using the form below. Accepted participants will receive a confirmation from the organizers. A link and a password to access the workshop sessions will be sent a few days before the event. Please note that the maximum number of participants is limited to 300 for technical reasons. There is no registration fee.
