Exploring electronic band structure and collective excitations in quantum materials
Quantum materials are characterized by electronic band structures and various collective excitations (like phonons, etc). Understanding the interplay between the two provides an avenue to explore the mystery of quantum phenomena.
Angle-resolved photoemission spectroscopy (ARPES) has been instrumental in understanding of quantum phenomena by probing electronic band structures. High-resolution electron energy loss spectroscopy (HREELS) allows to understand various surface excitations, including molecular vibrations, phonons, plasmons, magnons, and excitons. Multichannel HREELS allows orders of magnitude faster measurements compared to traditional single channel HREELS. Multimodal characterization combining state-of-art HREELS and ARPES/XPS for the same sample using the same analyser enables to study the interplay between electronic band structure and collective excitations.
Discover how multimodal characterisation using HREELS and ARPES enhances your research, for example, electron-phonon coupling and topologically protected excitations. This seminar will also provide introduction to principles and applications of HREELS and ARPES.
