Abstract:Hybrid perovskites have great potential in photovoltaics
and photodetection.
Specially, two-dimensional (2D) hybrid perovskites have been discovered
to show distinctive applications in polarization-sensitive photodetection
due to their intrinsic anisotropy. Herein, we designed a new type
of 2D perovskite by introducing bifunctional alkylammonium as an organic
spacer, (β-Ala)4PbBr4 (1,
where β-Ala+ is 3-aminopropanoic), which has four
organic spacers in adjacent inorganic layers and adjacent organic
layers are … Show more
