3d transition metal doping of semiconducting boron carbides
The introduction metallocenes, in particular ferrocene (Fe(η-C5H5)2), cobaltocene (Co(η-C5H5)2), and nickelocene (Ni(η-C5H5)2), together with the carborane source molecule closo-1,2-dicarbadodecaborane, during plasma enhanced chemical vapor deposition, will result in the transition metal doping of semiconducting boron carbides. Here we report using ferrocene to introduce Fe dopants, and a semic...
متن کاملThe coadsorption and interaction of molecular icosahedra with mercury
We have investigated the changes in the electronic structure of molecu larly adsorbed orthocarborane fi lms, as a function of Hg co-adsorption, using photoe mission. The interaction between Hg and molecular orthocarborane is weak and results in the formation of some small aggregates of Hg. This behavior is very different from alkali metals interaction with molecular carborane fi lms and the int...
متن کاملThe incorporation of Nickel and Phosphorus dopants into Boron-Carbon alloy thin films
The structural and electronic properties of nickeland phosphorus-doped boron–carbon (B5C) alloy thin films grown by plasma-enhanced chemical vapor deposition have been examined. The Ni-doped boron–carbon alloys were grown using closo-1,2-dicarbadodecaborane (C2B10H12) as the boron–carbon source compound and nickelocene (Ni(C5H5)2) as the nickel source. The phosphorus-doped alloys were grown usi...
متن کاملMercury and C2B10 Icosahedra Interaction
We contrast the interaction of mercury with adsorbed orthocarborane films and semiconducting (dehydrogenated) boron carbide. Photoemission spectra reveal small shifts in orthocarborane (C2B10H12) molecular orbital binding energies as well as the shift in mercury 5d5/2 shallow core level binding energies, suggesting only small interaction between mercury and the molecular film. Mercury does, how...
متن کاملStabilization of boron carbide via silicon doping.
Boron carbide is one of the lightest and hardest ceramics, but its applications are limited by its poor stability against a partial phase separation into separate boron and carbon. Phase separation is observed under high non-hydrostatic stress (both static and dynamic), resulting in amorphization. The phase separation is thought to occur in just one of the many naturally occurring polytypes in ...
