Modeling Changes in Measured Conductance of Thin Boron Carbide Semiconducting Films Under Irradiation [PDF]

open access: yes, 2016
Semiconducting, p-type, amorphous partially dehydrogenated boron carbide films (a-B10C2+x:Hy) were deposited utilizing plasma enhanced chemical vapor deposition (PECVD) onto n-type silicon thus creating a heterojunction diode.

Fabrication of (a-nc) boron carbide thin films via chemical vapor deposition using ortho-carborane

open access: yesJournal of Asian Ceramic Societies, 2020
Amorphous-nanocrystalline (a-nc) boron carbide thin films were prepared by chemical vapor deposition (CVD) by using ortho-carborane as a single-source precursor for inertial confinement fusion (ICF) application.

HIGH-DENSITY BORON-CARBIDE CERAMICS

open access: yesNOVYE OGNEUPORY (NEW REFRACTORIES), 2018
Porous preforms of B4C + C and B4C + C + Si materials were impregnated by liquid (molten) silicon to obtain high-density product with a relative density of 99.0 % and porosity of 0.9%. Silicon impregnation was carried out by saturating the samples through the pores of the SiC + C sacrificial preforms.
