Highly modulated dual semimetal and semiconducting γ-GeSe with strain engineering
Abstract Layered hexagonal γ -GeSe, a new polymorph of germanium selenide (GeSe) synthesized recently, shows strikingly high electronic conductivity in its bulk form (even higher than graphite) while semiconducting in the case of monolayer (1L). In this work, by using first-principles calculations, we demonstrate that, different from its orthorhombic phases …
