Interplay between Electronic Structure, Chemical Bonding, and Lattice Symmetry in Bismuth Vanadate
Philip Schwinghammer, Franziska S. Hegner, Frederico P. Delgado +5
Bismuth vanadate (BiVO) is a prototypical oxide photocatalyst that occurs in both tetragonal and monoclinic scheelite phases with markedly different photocatalytic and photoele…
AlHfN Thin Films with Enhanced Piezoelectric Responses for GHz Surface Acoustic Wave Devices
Laura I. Wagner, Verena Streibel, Esperanza Luna +9
Ternary compounds obtained by alloying wurtzite AlN with transition metals have emerged as promising materials with significantly enhanced piezoelectric characteristics relative to…
Quantifying Thermal, Photovoltage, and Defect Contributions to Transient Absorption of TaN Photoanodes
Johannes Dittloff, Lukas M. Wolz, Matthias U. Quintern +4
TaN is among the most intensively studied photoanode materials for solar-driven water oxidation, yet its performance often remains limited by short carrier lifetimes an…
Ultrafast light-induced formation of a metastable hidden state in bismuth vanadate
Viktoria F. Kunzelmann, Verena Streibel, Philip Schwinghammer +24
Bismuth vanadate (BiVO) is a key photocatalyst for solar fuel applications, yet fundamental questions remain regarding the nature of photogenerated polaronic states and the lat…
Atomically Flat Dielectric Patterns for Band Gap Engineering and Lateral Junction Formation in MoSe Monolayers
Philipp Moser, Lukas M. Wolz, Alex Henning +9
Combining a precise sputter etching method with subsequent AlO growth within an atomic layer deposition chamber enables fabrication of atomically flat lateral patterns of SiO$_…
