Control of charge transport in hybrid 2D perovskite heterostructures with organic semiconducting and ion-conducting interlayers (B05)

• Subject Area: Solid State and Surface Chemistry, Material Synthesis ; Experimental Condensed Matter Physics
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 492723217

This project (Herink/Kühne) employs 2D perovskites to study and understand photo-induced electronic transport in 2D confinement by introducing semi- and ion-conducting molecular interlayers into the hybrid organic-perovskite heterostructures. Variations of the perovskite thickness will control the free-carrier generation and the interface-dominated electron transport within the confined layers. We will study the carrier mobilities and implement multiple methods to separate charge generation and long-range transport. Using near-field techniques, we will study the impact of intrinsic structural inhomogeneities. Along with electron transport, we will also study the role of ionic conductivity and ion-doping in the interlayers.
