Stimulated by the recent discovery of bilayer nickelate high-Tc superconductor, we have (re-)started investigating the possibility of superconductivity in the single layer nickelate. However, T-structure (K₂NiF₄-type) La₂NiO₄ does not exhibit superconductivity. In stead of this material, we have investigated T’ phase of the same chemical formula to explore the possibility of superconductivity employing first-principles calculation. As the other procedures, we have evaluated the enegitical and the dynamical stability of the crystal structure of target compounds.
