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 ]. Bismuth is a chemical element with the symbol Bi and atomic number 83.
