WebRemarkably, the nontrivial energy gap can be as large as 464 meV for $\alpha$-bismuthene, indicating the high possibility of room-temperature observation of the doubled quantum spin Hall effect. WebMar 1, 2024 · Synthesis of few-layer bismuthene hexagons. In a typical synthesis, BiCl 3 (315 mg, 1 mmol) is added in a 100 mL three-necked flask. Once the powder is under argon DDT (4 mL) is added, and after that, the solution is put under vacuum until the salt is absolutely dissolved. Subsequently, ODE (6 mL) is added under argon.
