Unconventional incommensurate epitaxy of superconducting FeSe films on SrTiO${}_3$

M. Klement, K. M. Fijalkowski, M. Kamp +2

We present a combined X-ray diffraction and transmission electron microscopy study of superconducting FeSe/FeTe multilayers grown by molecular beam epitaxy on SrTiO${}_3$(001) substr…
