Abstract:

A novel, facile and cost-effective approach to the synthesis of boron nanostructures comprising of a mixture of boron nanotubes BNTs and nanofibers BNFs was developed under this contract. A method of nitrogen doping the BNTs and BNFs was also demonstrated. A key feature of this work is the use of a solid instead of a gaseous boron precursor for the synthesis of boron nanotubes and boron nanofibers. Two solid boron precursors, MgB2 and MgBH42, were used in the synthesis performed as discussed in the report. Because of the e-beam instability of the boron nanostructures prepared using MgBH42, further work needs to be done in characterizing samples made by this method
