Insights into the Structural and Orientational Ordering of 2D Metal Halide Perovskites
Mustafa Mahmoud Aboulsaad, German Alvarez Carrero, Trupthi Devaiah Chonamada +4
Metal halide perovskite nanoplatelets combine quantum confinement with structural anisotropy, yet how thickness and processing govern their internal crystal lattice versus collecti…
Temperature Dependent Magnetic and Structural Properties of Al Substituted Nanostructured Ferrites with Large Coercive Fields
P. Maltoni, R. K. Dokala, P. Pramanik +12
We report a comprehensive study of the temperature-dependent structural, magnetic, vibrational, and dielectric properties of Al-substituted M-type hexaferrites SrFeAlO…
Confinement-Driven Exciton Behavior in 2D Halide Perovskites from Dielectric-Dependent Hybrid Methods
Rafael B. Araujo, Mustafa Mahmoud Aboulsaad, Sebastian E. Reyes-Lillo +1
Understanding how dielectric anisotropy governs excitonic behavior in two-dimensional (2D) halide perovskites is critical for predicting and engineering their optoelectronic proper…
Symmetry-driven phonon confinement in 2D halide perovskites
Mustafa Mahmoud Aboulsaad, Olivier Donzel-Gargand, Rafael B. Araujo +1
Quantum confinement not only reshapes electronic states but also reorganizes the vibrational landscape of low-dimensional semiconductors. In halide perovskites, however, the role o…
Phonon-Mediated Chirality Transfer from Organic Cation to Inorganic lattice in Hybrid Perovskites
Sankaran Ramesh, Prasenjit Mandal, Rafael Araujo +6
Two-dimensional hybrid metal halide perovskites combine spin-orbit coupling, soft lattice dynamics, and molecular tunability, making them promising platforms for chiral optoelectro…
Coherent Phonons, Localization and Slow Polaron Formation in Lead-free Gold Perovskite
Sankaran Ramesh, Yonghong Wang, Pavel Chabera +5
Lead-free metal halide perovskites are emerging as less-toxic alternatives to their lead-based counterparts. However, their applicability in optoelectronic devices is limited, and…
