FitED: A User-Centric, Extensible Software Environment for Robust Peak-Profile and General Functional Data Fitting
Mustafa Mahmoud Aboulsaad
Reliable parameter extraction from experimental data is essential for quantitative analysis across spectroscopy, diffraction, photoluminescence, chromatography, microscopy, and tim…
Unveiling the Thermal and Aqueous Stability of 1D Lepidocrocite Titania
Risha A. Iythichanda, Sukanya Maity, Mustafa M. Aboulsaad +3
One dimensional lepidocrocite titanium dioxide filaments are investigated with respect to their thermal and aqueous stability. Structural and phase evolution are examined using in…
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…
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…
