TL;DR: In this paper, the effects of a KCN etch of the CZTS absorber prior to CdS deposition on the band alignment at the respective interface were studied.
Journal ArticleDOI
Electronic Surface Level Positions of WO3 Thin Films for Photoelectrochemical Hydrogen Production
Lothar Weinhardt,Monika Blum,and M. Bär,Clemens Heske,Brian Cole,and B. Marsen,Eric L. Miller +6 more
TL;DR: In this paper, photoelectron spectroscopy and inverse photoemission were used to investigate polycrystalline WO3 thin films for photoelectrochemical hydrogen production.

Isotope and temperature effects in liquid water probed by x-ray absorption and resonant x-ray emission spectroscopy
Oliver Fuchs,Michael Zharnikov,Lothar Weinhardt,Monika Blum,Monika Blum,Markus Weigand,Yan V. Zubavichus,Marcus Bär,Florian Maier,Jonathan D. Denlinger,Clemens Heske,Michael Grunze,Eberhard Umbach +12 more
TL;DR: It is proposed that the two components of liquid water are governed by the initial state hydrogen bonding configuration and ultrafast dissociation on the time scale of the O 1s core hole decay.
