Mercury and C2B10 Icosahedra Interaction

“…These latter results suggest that mercury interacts with the solid films of the dehydrogenated C 2 B 10 icosahedra (semiconducting boron carbide). This interaction is consistent with theory we have undertaken [18] and is different from any expectation that would result from the very weak interaction observed between mercury (Hg) and the molecular (hydrogenated C 2 B 10 ) orthocarborane.…”

The electronic structure of 1,2-PCB10H11 molecular films: a precursor to a novel semiconductor

“…The electronic structure of the molecular carborane fi lms is not always a good indicator of the semiconducting properties resultant boron-carbide C 2 B 10 H x , formed by the par tial dehydrogenation and deposition of corresponding car bide through PECVD [58,59]. Yet, for the n-type boron car bide formed from metacarborane (1,7-C 2 B 10 H 12 ) [7,17], the p-type boron-carbide, derived from the decomposition of orthocarborane (1,2-C 2 B 10 H 12 ) [7,17], the placement of the Fermi level in the electronic structure of the molecular fi lm does appear to be correlated.…”

3d transition metal doping of semiconducting boron carbides

“…Cobaltocene has been shown to dope PECVD grown semiconducting boron carbide [11]. Oddly enough, some other common semiconductor dopants, like Hg [12], do not dope PECVD grown semiconducting boron carbide at all.…”
