Temperature-dependent optical spectra of single-crystal (CHNH)PbBr cleaved in ultrahigh vacuum
Daniel Niesner, Oskar Schuster, Max Wilhelm +6
We measure temperature-dependent one-photon and two-photon induced photoluminescence from (CH3NH3)PbBr3 single crystals cleaved in ultrahigh vacuum. An approach is presented to ext…
Black TiO2 nanotubes formed by high energy proton implantation show noble-metal-co-catalyst free photocatalytic H2-evolution
Ning Liu, Volker Häublein, Xuemei Zhou +8
We apply high-energy proton ion-implantation to modify TiO2 nanotubes selectively at their tops. In the proton-implanted region we observe the creation of intrinsic co-catalytic ce…
Hydrogenated anatase: Strong photocatalytic H2 evolution without the use of a co-catalyst
Ning Liu, Christopher Schneider, Detlef Freitag +8
In the present work we show, how a high pressure hydrogenation of commercial anatase or anatase/rutile powder can create a photocatalyst for hydrogen evolution that is highly effec…
Giant Rashba Splitting in CH3NH3PbBr3 Organic-Inorganic Perovskite
Daniel Niesner, Max Wilhelm, Ievgen Levchuk +5
As they combine decent mobilities with extremely long carrier lifetimes, organic-inorganic perovskites have opened a whole new field in opto\-electronics. Measurements of their und…
