3d transition metal doping of semiconducting boron carbides

چکیده
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 semiconducting boron-carbide homojunction has been fabricated. The diode characteristics are very similar to those fabricated with Co and Ni doping.
