Structural, Mechanical, Electronic, and Magnetic Properties of LiO in Cesium Chloride, Rocksalt and Zinc-blende Structures
IYORZOR, BE & BABALOLA, IM
Abstract
The structural, mechanical, electronic, lattice dynamic and magnetic properties of LiO in
the Cesium Chloride (CsCl), Rocksalt (Rs) and Zinc-blende (ZB) structures is presented. The first-principles
calculations was implemented using the spin-polarized (DFT) approach. It was observed that LiO
compound exhibits ferromagnetic (FM) character at the equilibrium lattice constants in the three phases.
Applying the stability conditions for cubic phases, the calculations reveal that the compound is
mechanically unstable. The study also confirmed that except for the ZB structure which exhibits the brittle
property, the others portray ductile nature and they are of good plasticity. We find also that the LiO
structures can be synthetized, and their half-metallic property can be preserved over a broad ambit of the
lattice contraction which offers the possibility to epitaxially grow such compound on a wide range of
semiconductors.
