WebBismuthene, a 2D layer of Bi atoms in a honeycomb structure, has recently attracted strong attention because of its record-large nontrivial gap, which is due to the strong spin-orbit coupling... WebBismuth (Bi) is a semimetal with unique physical properties. Its electron energy dispersion is very anisotropic, the effective masses of the carriers are small, and their free-flight distances are large. When the Bi layer is thinned to approximately 30 nm, it is converted from a semimetal to a semiconductor [ 1 ].

A detailed description of the crystal and the band structure of Si, together with the methods for obtaining the band structure are discussed in Section 3.2. Finally, the effect of strain on the band structure is presented in Section 3.3. Webphosphorus structure, α-form). The widely investigated α-phosphorene is best known example, however, α-arsenene, α-antimonene, α-bismuthene and α-bismuth antimonidene can be synthesized.
