Layered hybrid perovskites (LPKs) have emerged as a viable solution to address perovskite
stability concerns and enable their implementation in wide‐scale energy harvesting. Yet …

Layered two-dimensional (2D) lead halide perovskites are a class of quantum well (QW)
materials, holding dramatic potentials for optical and optoelectronic applications. However …

In this review, we discuss the rich ultrafast response at terahertz (THz) frequencies of two-
dimensional (2D) materials. Thanks to their unique optoelectronic properties and …

Organic-inorganic hybrid metal halide perovskites (MHPs) have attracted tremendous
attention for optoelectronic applications. The long photocarrier lifetime and moderate carrier …

We investigate the effect of metal cation substition on the excitonic structure and dynamics in
a prototypical Ruddlesden–Popper metal halide. Through an in-depth spectroscopic and …

Rapid advances in perovskite photovoltaics have produced efficient solar cells, with stability
and duration improving thanks to variations in materials composition, including the use of …

Changes in bond types and the reversible switching process between metavalent and
covalent bonds are related to the operating mechanism of the phase-change (PC) behavior …

We investigate the hot carrier and exciton dynamics in two-dimensional (2D) metal halide
perovskites using time-resolved spectroscopy. 2D perovskite films were prepared with and …

As for many technological applications, excitation transport determines their performance,
we investigate the THz conductivity of electrons, holes, excitons, and trions in 2D …

Converting CO2 into valuable solar fuels through photocatalysis has been considered a
green and sustainable technology that is promising for alleviating global warming and …
