Possible high thermoelectric power factor in alkali-metal-intercalated BC${}_3$: anisotropic multiple valleys originating from the van Hove singularity of graphene

Ryutaro Enami, Kazuhiko Kuroki, Masayuki Ochi

We theoretically investigate the electronic structure of monolayer BC${}_3$ and find that it hosts anisotropic multiple valleys originating from the splitting of the van Hove singula…
