arXiv preprint arXiv:1706.00314, 2017•arxiv.orgSolvothermal intercalation of ethylenediamine molecules into FeSe separates the layers by
1078 pm and creates a different stacking. FeSe (en) 0.3 is not superconducting although
each layer exhibits the stripe-type crystal structure and the Fermi surface topology of
superconducting FeSe. FeSe (en) 0.3 requires electron-doping for high-Tc similar to
monolayers of FeSe@ SrTiO3, whose much higher Tc may arise from the proximity of the
oxide surface.
