Abstract
Section titled āAbstractāHere we examine physical properties of heavily boron-doped sp<sup>3</sup>-hybridized carbon allotropes: cubic diamond, hexagonal diamond, and body centered tetragonal C<sub>4</sub>. The structural similarity between cubic diamond and hexagonal diamond leads to similar responses to substitutional boron doping. On the other hand, body centered tetragonal C<sub>4</sub> exhibits distinct structural and electronic properties because of its characteristic structure. Our study also shows that the superconducting transition temperatures up to 60 K are possible in heavily doped carbon materials despite their various atomistic structures.
