Energy level alignment of vacancy-ordered halide double perovskites
Ibrahim Buba Garba, George Volonakis
Vacancy-ordered double perovskites have emerged as lead-free alternatives, offering remarkable stability and compositional tunability for optoelectronic applications. In this study…
Three-Dimensional to Layered Halide Perovskites: A Parameter-Free Hybrid Functional Method for Predicting Electronic Band Gaps
Ibrahim Buba Garba, Lorenzo Trombini, Claudine Katan +4
Accurate prediction of electronic band gaps in halide perovskites using density functional theory is crucial for optoelectronic applications. Standard hybrid functionals like HSE a…
The Emergence of Anisotropic Superconductivity in the Nodal-line Semi-metal TlTaSe2
Mukhtar Lawan Adam, Ibrahim Buba Garba, Sulaiman Muhammad Gana +7
TlTaSe2 is a non-centrosymmetric quasi-2D crystal semi-metal hosting nodal-line topological features protected by mirror-reflection symmetry. Here, we investigated the superconduct…
Reciprocal space temperature-dependent phonons method from ab-initio dynamics
Ibrahim Buba Garba, Tommaso Morresi, Charles Bouillaguet +2
We present a robust reciprocal-space implementation of the temperature-dependent effective potential method. Our implementation can scale easily to large cell and long sampling tim…
Tuning Superconductivity and Charge Density Wave Order in 2H-TaSe2 by Modulating the Van Hove Singularity
Mukhtar Lawan Adam, Ibrahim Buba Garba, Abba Alhaji Bala +3
Tantalum diselenide (TaSe2) is an exciting material that hosts charge density wave order (CDW) and superconductivity. Thus, providing a playing field for examining the interactions…
