Quantum Materials Webinar: From Band Structure to Collective Excitations | Scienta Omicron

Quantum materials exhibit complex electronic band structures and a wide range of collective excitations like phonons. Understanding how these excitations interact with electronic states is essential for revealing the mechanisms behind emergent quantum phenomena.

Scienta Omicron provides advanced surface science solutions for probing both electronic band structures and collective excitations. Angle-resolved photoemission spectroscopy (ARPES) has become an indispensable tool for mapping electronic band structures, while high-resolution electron energy loss spectroscopy (HREELS) enables investigation of surface excitations including phonons, plasmons, magnons, excitons, and molecular vibrations. Our multichannel HREELS technology delivers orders-of-magnitude faster data acquisition than conventional single-channel instruments, enabling efficient measurements without compromising energy resolution.

In this webinar, we will present new high-resolution HREELS results demonstrating the performance and capabilities of the latest multichannel HREELS instrumentation. We will also discuss how integrating HREELS with ARPES/XPS on the same platform enables comprehensive multimodal characterization of quantum materials using the same sample and analyser.

Join us to discover how combined ARPES and HREELS measurements provide unique insights into the relationship between electronic structure and collective excitations, while gaining an introduction to the principles and applications of both techniques.
