Low Born effective Charges, High Covalency and Strong Optical Activity in $X_{3}^{2 +}$ Bi $^{3 -}$ N $^{3 -}$ ( $X$ =Ca,Sr,Ba) $in v er se$ -perovskites

Jasmine Wakini, Carolyne Songa, Stephen Chege +6

We compute for the first time a complete charge analysis (Bader and Born effective) on $X_{3}^{2 +}$ Bi $^{3 -}$ N $^{3 -}$ ( $X$ =Ca,Sr,Ba). The crystals show a great electron sharing with l…

Ab initio study of structural properties and dynamical stability of C $_{3}$ N $_{2}$ encapsulating H guest atom

George S. Manyali

We have investigated the structural properties and dynamical stability of C $_{3}$ N $_{2}$ 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 $^{\circ}$ domain walls in PbTiO $_{3}$ 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 $^{\circ}$ domain walls in isolated free-standing PbTiO $_{3}$ sl…

Comparison of band-fitting and Wannier-based model construction for WSe $_{2}$

James Sifuna, Pablo García-Fernández, George S. Manyali +2

Transition metal dichalcogenide materials $M X_{2} (M = M o, W; X = S, S e)$ 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 $_{3}$ [C $_{2}$ N] $_{2}$

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 $_{3}$ [C $_{2}$ N] $_{2}$ crystal. The nearly colorless, centros…
