Comparative Raman study of Ruddlesden-Popper nickelates and the monolayer-trilayer polymorph

Vignesh Sundaramurthy, Abhi Suthar, Pascal Puphal +12

Ruddlesden-Popper (RP) nickelates have attracted intense interest following the discovery of superconductivity in several members of the series, including bilayer (BL) LaNi

Lattice dynamics of the infinite-layer nickelate LaNiO

Shohei Hayashida, Vignesh Sundaramurthy, Wenfeng Wu +8

Infinite-layer (IL) nickelates have rapidly emerged as a new class of superconductors. However, due to the technical challenges of their topotactic synthesis, they have so far been…
