Abstract

We apply a novel chemical capacitor setup to facilitate metallization of ionic hydrides, LiH and MgH2. It turns out that the amount of holes doped to a single layer of these materials may reach 0.72 per H atom without structure collapse; concomitant maximum TC values exceed 17 K in the absence of external pressure for 0.31-hole-doped LiH supported on the LiBaF3 perovskite.
