A decade of Density Functional Theory in Kenya
George S. Manyali
The African School Series on Electronic Structure Methods and Applications (ASESMA) has had a positive impact on growth of computational material science in Kenya, visibility of Ke…
Ab Initio Study of KCuP Material for Photovoltaic Applications
Mwende Mbilo, George S. Manyali, Robinson J. Musembi
Search for efficient materials for application in the fields of optoelectronics and photovoltaics are active areas of research across the world. The potential of compounds such as…
Low Born effective Charges, High Covalency and Strong Optical Activity in BiN (=Ca,Sr,Ba) -perovskites
Jasmine Wakini, Carolyne Songa, Stephen Chege +6
We compute for the first time a complete charge analysis (Bader and Born effective) on BiN (=Ca,Sr,Ba). The crystals show a great electron sharing with l…
Ab initio study of structural properties and dynamical stability of CN encapsulating H guest atom
George S. Manyali
We have investigated the structural properties and dynamical stability of CN hosting hydrogen as a guest atom. The calculations were performed using the density functional…
First-principles study of two-dimensional electron and hole gases at the head-to-head and tail-to-tail 180 domain walls in PbTiO ferroelectric thin films
James Sifuna, Pablo García-Fernández, George S. Manyali +2
We study from first-principles the structural and electronic properties of head-to-head (HH) and tail-to-tail (TT) 180 domain walls in isolated free-standing PbTiO sl…
Comparison of band-fitting and Wannier-based model construction for WSe
James Sifuna, Pablo García-Fernández, George S. Manyali +2
Transition metal dichalcogenide materials are being thoroughly studied due to their novel two-dimensional structure, that is associated with exceptional opti…
Ab initio study on Quasi-Binary Acetonitriletriide Sr[CN]
James Sifuna, George S. Manyali, Elicah Wabululu +3
We report using density functional theory (DFT), the ground-state properties of the recently synthesized and characterized Sr[CN] crystal. The nearly colorless, centros…
Low compressible BPN
George S. Manyali, James Sifuna
Using first principles calculation, the structural and mechanical properties of BPN which adopts an orthorhombic structure with space group Pna2 (no. 33), were determin…
A DFT study of mechanical properties of hcp Rhenium
George S. Manyali
In the present paper, hcp Re was investigated in terms of its structural, elastic, mechanical and thermodynamic properties using density-functional theory (DFT). The local density…
