Probing a divergent van Hove singularity of graphene with a Ca${}_2$N support: a layered electride as a solid-state dopant

Takeshi Inoshita, Masaru Tsukada, Susumu Saito +1

Layered electrides, as typified by Ca${}_2$N, are a new class of quasi-two-dimensional materials with low work functions. Using first-principles calculations, we have shown that a gr…
