Title

Diffusional organic cation dynamics in 2D hybrid inorganic-organic perovskites

Abstract

This proposal concerns the investigation of the localised diffusional dynamics of organic molecular cations in two selected two-dimensional (2D) hybrid inorganic-organic perovskites by quasielastic neutron scattering. We propose to use both IN16b and IN5, which will provide complementary information in terms of the time-scales probed. The overall aim of the proposal is to provide a detailed description of the organic cation dynamics over a wide temperature range in these type of materials, and to understand the impact of this on the materials' optoelectronic properties.
