| description | High quality Boron Nitride Nanotubes (BNNTs) may be synthesized by heating a boron melt target via one or more laser diodes, including laser diode stacks. The use of a diode stack and beam shaping optics to irradiate the boron melt eliminates the need for a conventional laser cavity as has been employed with previous embodiments. The diode arrangements facilitate managing power distribution on the born melt(s), nitrogen gas flows, and blackbody radiation that drive the BNNT self-assembly process. These parameters may be used for controlling the proportions and characteristics of boron species, a-BN particles, h-BN nanocages, and h-BN nano sheets in the as-synthesized BNNT material while enhancing the quality of the BNNTs. |
