Mechanical strength and flexibility in $$\alpha '$$ α ′ -4H borophene
Abstract Very recently, a novel phase of hydrogenated borophene, namely $$\alpha '$$ α ′ -4H, has been synthesized in a free-standing form. Unlike pure borophenes, this phase shows very good stability in the air environment and possesses semiconducting characteristics. Because of the interestin...
