Is Boron a semiconductor?

Yes, Boron is a semiconductor. Its has an indirect bandgap. You can look into the band structure calculation for alpha rhombohedral boron published in following journal: [1] H. read more

Boron is not a semiconductor, it is a dopant for semiconductors such as Silicon(Si) and Germanium. The process of adding substances to a pure semiconductor for the purposes of modulating its electrical properties is known as doping. read more

Semiconductors. Boron is a useful dopant for such semiconductors as silicon, germanium, and silicon carbide. Having one fewer valence electron than the host atom, it donates a hole resulting in p-type conductivity. Traditional method of introducing boron into semiconductors is via its atomic diffusion at high temperatures. read more

Substituting a boron atom (with three valence electrons) for a silicon atom in a silicon crystal leaves a hole (a bond missing an electron) that is relatively free to move around the crystal. Other semiconductor materials. read more
