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…
