1.1 Boron-Rich Framework and Electronic Band Framework

(Calcium Hexaboride)

Calcium hexaboride (CaB ₆) is a stoichiometric metal boride belonging to the class of rare-earth and alkaline-earth hexaborides, differentiated by its special combination of ionic, covalent, and metallic bonding features.

Its crystal structure takes on the cubic CsCl-type latticework (room group Pm-3m), where calcium atoms occupy the dice edges and a complicated three-dimensional framework of boron octahedra (B ₆ systems) resides at the body center.

Each boron octahedron is composed of six boron atoms covalently adhered in an extremely symmetrical setup, developing an inflexible, electron-deficient network stabilized by cost transfer from the electropositive calcium atom.

This charge transfer causes a partly filled up transmission band, granting CaB six with abnormally high electric conductivity for a ceramic material– like 10 ⁵ S/m at room temperature– in spite of its huge bandgap of about 1.0– 1.3 eV as identified by optical absorption and photoemission research studies.

The origin of this paradox– high conductivity existing side-by-side with a large bandgap– has been the topic of extensive research, with theories suggesting the existence of innate issue states, surface area conductivity, or polaronic transmission mechanisms including local electron-phonon combining.

Current first-principles calculations support a model in which the transmission band minimum acquires mostly from Ca 5d orbitals, while the valence band is dominated by B 2p states, developing a narrow, dispersive band that promotes electron flexibility.
