XUV Lab (Lab2 - A637)

XUV lab is one of our latest lab, where we have coupled a home-built high harmonic beamline to a time-of-flight momentum microscope, to do space, time and angle resolved photoemission spectroscopy (tr-µ-ARPES). We have our system up and operational since early 2020. In this lab, we have focused our research on the understanding of excitonic structure and exciton dynamics in 2D materials and their heterostructure [1-3].
