Induced Half-Metallicity and Gapless Topological Superconductivity in the CrI$_3$-Pb Interface

24 Sep 2020 Margalit Gilad Yan Binghai Oreg Yuval

We study a two-dimensional heterostructure comprised of a monolayer of the magnetic insulator chromium triiodide (CrI$_3$) on a superconducting lead (Pb) substrate. Through first-principles computation and a tight-binding model, we demonstrate that charge transfer from the Pb substrate dopes the CrI$_3$ into an effective half-metal, allowing for the onset of a gapless topological superconductivity phase via the proximity effect...
