“…61,62 This is because electrons below the Fermi level cannot go into the empty states of the conduction bands because a local DOS minimum at the Fermi level serves as an energy barrier ( via the distinctive separation of bonding and anti-bonding states). 63 According to our computed PDOS, all i -MAX structure's valence and conduction bands that cross the Fermi level are mostly contributed by Mo(d) states with some contribution from Sc(d) states. It is worth mentioning that the presence of low-dispersive transition metal d-like bands near the Fermi level plays a vital role for the optical conductivity in these structures.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
