Layered hybrid perovskites show diverse physical properties and exceptional functionality; however, from a materials science viewpoint, the co-existence of lattice order and structural disorder can hinder the understanding of such materials. Lattice dynamics can be affected by dimensional engineering of inorganic frameworks and interactions with molecular moieties in a process that remains unknown.
. However, it remains to be determined if these properties can persist to the single-layer limit.
In this new work, Zhang and colleagues presented a joint experimental and theoretical study to uncover the origin of the structural complexity of two-dimensional hybrid perovskites. They used steady state and ultrafast experiments to identify unique fingerprints to distinguish the structural dynamics of hybrid lattices in the crossover from quasi-2D to 2D.
THz Kerr effect spectroscopy measurements. The single-cycle THz pump is focused on 2DHP single crystal to induce a nonlinear response. The time-delayed 800 nm probe pulse is polarized at 45° relative to the vertical THz polarization and the transiently depolarized signal is measured by a balanced detection scheme. HWP, half-wave plate. Time-resolved THz-Raman signals for both n=1 and n=2 2DHPs at various temperatures.
