We have succeeded in the fabrication of a boron-carbide/boron diode on an aluminum substrate, and a boron-carbide/boron junction field effect transistor. Our results suggest that with respect to the approximately 2 eV band gap pure boron material, 0.9 eV band gap boron-carbide (B5C) acts as a p-type material. Both boron and boron-carbide (B5C) thin films were fabricated from single source borane cage molecules using plasma enhanced chemical vapor deposition (PECVD). Epitaxial growth does not appear to be a requirement.
