Halide Perovskite Nanopillar Photodetector

ACS Nano, 2018
Numerous studies have reported the use of halide perovskites as highly functional light-harvesting materials. The development of optimized compositions and deposition approaches has led to impressive improvements; however, no noticeable breakthrough in performance has been observed for these materials recently.

Photorechargeable Hybrid Halide Perovskite Supercapacitors

ACS Applied Materials & Interfaces, 2022
Current approaches for off-grid power separate the processes for energy conversion from energy storage. With the right balance between the electronic and ionic conductivity and a semiconductor that can absorb light in the solar spectrum, we can combine energy harvesting with storage into a single photoelectrochemical energy storage device.

Halide Perovskite Lasers

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 ...

Organometal Halide Perovskite Artificial Synapses

Advanced Materials, 2016
Organometal halide perovskite synaptic devices are fabricated; they emulate important working principles of a biological synapse, including excitatory postsynaptic current, paired-pulse facilitation, short-term plasticity, long-term plasticity, and spike-timing dependent plasticity. These properties originate from possible ion migration in the ion-rich

Ferroelectricity in Ultrathin Halide Perovskites

Nano Letters
Ferroelectricity 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)
