Structural Evolution from Hyper-Honeycomb to Honeycomb Networks and Superconductivity in LaPt${}_x$Si${}_{2-x}$

Sitaram Ramakrishnan, Tatsuya Yamakawa, Ryohei Oishi +11

We report the crystal structures and superconductivity (SC) of LaPt${}_x$Si${}_{2-x}$ ($0.5\le x\le 1.0$) that are solid solutions of LaSi${}_2$ and LaPtSi with centrosymmetric t…
