text: Beyond this semimetallic character that arises from the electronic band structure near the Fermi level, it is worth mentioning that Bi has a rich variety of lower-lying energy bands as demonstrated in the band diagram of bismuth (Figure 1(c)), which have been predicted early theoretically  and probed by photoelectron or optical spectroscopy.
