Spin-split bands cause the indirect band gap of (CHNH)PbI: Experimental evidence from circular photogalvanic effect
Daniel Niesner, Martin Hauck, Shreetu Shrestha +7
Long carrier lifetimes and diffusion lengths form the basis for the successful application of the organic-inorganic perovskite (CHNH)PbI in solar cells and lasers. The…
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…
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…
One-dimensional potential for image-potential states on graphene
P. L. de Andres, P. M. Echenique, D. Niesner +2
In the framework of dielectric theory the static non-local self-energy of an electron near an ultra-thin polarizable layer has been calculated and applied to study binding energies…
Unoccupied Topological States on Bismuth Chalcogenides
D. Niesner, Th. Fauster, S. V. Eremeev +9
The unoccupied part of the band structure of topological insulators BiTeSe () is studied by angle-resolved two-photon photoemission and density functiona…
Trapping Surface Electrons on Graphene Layers and Islands
D. Niesner, Th. Fauster, J. I. Dadap +7
We report the use of time- and angle-resolved two-photon photoemission to map the bound, unoccupied electronic structure of the weakly coupled graphene/Ir(111) system. The energy,…
