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…

Interplay of lattice distortion and bands near the Fermi level in $A$ TiO $_{3}$ ( $A$ =Ca, Sr, Ba)

Patrick Ning'i, Stephen Chege, James Sifuna +1

The structural and electronic properties of $A$ TiO $_{3}$ ( $A$ =Ca, Sr, Ba) have been investigated under strain-free situation and with realistic constraints using first-principles cal…
