Fabrication of tetragonal FeSe - FeS alloy films with high sulfur contents by alternate deposition

Kohei Fujiwara, Junichi Shiogai, Atsushi Tsukazaki

We report the synthesis of tetragonal ${\mathrm{FeS}}_x{\mathrm{Se}}_{1-x}$ films ($x\le 0.78$) by pulsed-laser deposition. To fabricate the tetragonal alloy films with tetragonal Fe…
