Web6 okt. 2024 · Here, we report that hydrogenated borophene can be grown on the fluorine-doped tin oxide glass substrate. The phase of the obtained borophene is well consistent with the predicted semiconducting δ5 -boron sheet. Furthermore, a vertical heterojunction ultraviolet detector based p-borophene/n-zinc oxide was fabricated. WebHydrogenation acts as a robust passivation scheme for borophene with multiple borophane polymorphs, suppressing measurable oxidation for several days following ambient exposure. Since this hydrogenation can be reversibly removed through thermal annealing, borophane can be returned to pristine borophene following ambient … kooth online referral
