Abstract
Attosecond time-resolved photoemission from the differently terminated BiTeCl surfaces yield a photoelectron streaking that cannot be explained by bulk propagation effects alone. Instead, the atomic scale electronic structure and dynamical screening for both surface terminations have to be taken into account.
Highlights
Generation of intense attosecond light pulses and their application in photoelectron streaking spectroscopy allows capturing the photoemission process from different initial states with unprecedented temporal resolution [1]
