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.

Excitons in CsPbBr3 Halide Perovskites

The Journal of Physical Chemistry Letters, 2021
Excitons 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 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)

Metal halide perovskites

Η ολοένα αυξανόμενη ανάγκη παρακολούθησης ατμοσφαιρικών ρύπων, τοξικών χημικών και εκρηκτικών αερίων, έχει ωθήσει σε σημαντικές εξελίξεις στον τομέα της τεχνολογίας ανίχνευσης αερίων. Ωστόσο, οι συμβατικοί αισθητήρες αντιμετωπίζουν συχνά περιορισμούς, όπως χαμηλή ευαισθησία και επιλεκτικότητα.

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 ...
