Polarons in Halide Perovskites: A Perspective
The Journal of Physical Chemistry Letters, 2020Metal halide perovskites (MHPs) have rapidly emerged as leading contenders in photovoltaic technology and other optoelectronic applications owing to their outstanding optoelectronic properties. After a decade of intense research, an in-depth understanding of the charge carrier transport in MHPs is still an active topic of debate.

Rethinking the A cation in halide perovskites
Science, 2022The A cation in ABX 3 organic-inorganic lead halide perovskites (OLHPs) was conventionally believed to hardly affect their optoelectronic properties. However, more recent developments have unraveled the critical role of the A cation in the regulation of the physicochemical and optoelectronic properties of OLHPs.

Excitons in CsPbBr3 Halide Perovskites
The Journal of Physical Chemistry Letters, 2021Excitons in Bridgman grown halide perovskite CsPbBr3 single crystals were examined using photoluminescence (PL) spectroscopy to determine the nature of the electronic states. The photoluminescence intensity was strongly temperature-dependent and depended upon the specific exciton band.

Ferroelectricity in Ultrathin Halide Perovskites
Nano LettersFerroelectricity has recently been demonstrated in germanium-based halide perovskites. We use first-principles-based simulations to study 4-18 nm CsGeBr3 films and develop a theory for ferroelectric ultrathin films. The theory introduces (i) a local order parameter, which identifies phase transitions into both monodomain and polydomain phases, and (ii)

Conference on Lasers and Electro-Optics, 2017
Solution-processed halide perovskites possess exceptional photovoltaic properties. Amazingly, these materials are also outstanding optical gain media. Amplified spontaneous emission and lasing have been demonstrated in various halide perovskite configurations and nanostructures with wavelengths tunable over the visible and infrared (400–1000 nm ...
