DESCRIPTION: Perovskite materials with stoichiometry ABX<sub>3</sub> 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 ((C<sub>6</sub>H<sub>5</sub>C<sub>2</sub>H<sub>4</sub>NH<sub>3</sub>)<s
 ub>2</sub>PbI<sub>4</sub>) with phenethylammonium cations on the A-site an
 d compare the differences towards the benchmark case of three-dimensional 
 (3D) hybrid perovskites\, CH<sub>3</sub>PbI<sub>3</sub>. 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.\nSpeaker: Julian Gebhardt
