Boronated carbons : structural characterization and low temperature physical properties of disordered solids

BxC1-x compounds (x up to 0.25) were prepared by the thermal CVD technique. The aim was to better characterise some specific boron-rich compositions that are not yet satisfactorily described. Both structural and physical properties, including low temperature dc resistivity, dynamic and static magnet...

More Information
Summary:BxC1-x compounds (x up to 0.25) were prepared by the thermal CVD technique. The aim was to better characterise some specific boron-rich compositions that are not yet satisfactorily described. Both structural and physical properties, including low temperature dc resistivity, dynamic and static magnetic susceptibilities, specific heat and thermal conductivity, were studied. The final purpose was to correlate the structural disorder, both positional and substitutional, with particular electronic and vibrational properties deduced from low temperature experiments. 52 refs.
