DESCRIPTION: Perovskite materials with stoichiometry ABX3 are a
rich family of ionic compounds with many technological interesting propert
ies. They can be traditional inorganic\, metal per- ovskites or hybrid per
ovskites with one organic cation. In this talk I want to discuss some resu
lts of a special modification of the latter kind\, the so-called layered p
erovskites. This family of structures is currently rediscovered\, and we r
eport on the geometrical and electronic structure of one promising candida
te ((C6H5C2H4NH3)2PbI4) with phenethylammonium cations on the A-site an
d compare the differences towards the benchmark case of three-dimensional
(3D) hybrid perovskites\, CH3PbI3. The influence of
varying the cation as well as changing the dimensionality from 3D to 2D sy
stems is discussed by comparing bulk and monolayer structures of both syst
ems. In addition\, insight into the optical behavior and the observed elec
tron-phonon coupling will be given.\nVortragende(r): Julian Gebhardt
