Since the discovery of Rochelle salt a century ago, ferroelectric materials have been
investigated extensively due to their robust responses to electric, mechanical, thermal …

2D hybrid perovskites with strong spin–orbit coupling (SOC) and structural asymmetry
represent a new class of quantum materials that can potentially display coexisting …

The Rashba effect, ie, the splitting of electronic spin‐polarized bands in the momentum
space of a crystal with broken inversion symmetry, has enabled the realization of spin …

The giant spin–orbit coupling (SOC) of a heavy lead element significantly extends charge
carrier lifetimes of lead halide perovskites (LHPs). The physical mechanism remains unclear …

Here we review an emerging class of 2D layered metal-halide perovskites that exhibit
important photophysical behavior involving inorganic exciton-to-molecular triplet energy …

Two-dimensional (2D) Dion–Jacobson (DJ) organic–inorganic hybrid halide perovskites
hold great potential for optoelectronics and solar cells. Interestingly, experimental excited …

Hybrid lead halide perovskites have progressively overcome the horizon of materials for
novel, highly efficient solar cells and are now proposed for a variety of optoelectronic …

Chirality transfer from organic chiral molecules to lead halides is theorized as the origin of
the strong Rashba‐Dresselhaus effect causing large circular dichroism (CD) and circularly …

The pivotal impact of organic cation rotation may result in structural complexity in two-
dimensional (2D) halide-based hybrid perovskites. The crucial role of the orientation of the …
