✦ Synopsis


Boron-and silicon-doped carbon clusters of the type BmC . (m = 1-4) and Si,,C, (m = 1, 2) have been produced via the laser-vaporization cluster beam technique. The observed features of the intensity distribution in mass spectra suggest that B atoms can be incorporated into the clusters with much higher efficiency than Si atoms. The mass spectral evidence is also consistent with the idea that SiC,(n >~ 30) and BC,(n >~ 30) clusters have a silicon-and boron-heterofullerene structure, respectively.

Two methods have been employed to prepare boron-doped carbon materials. One method utilized ion implantation to dope the surface region of vitreous carbon with up to 12 atomic % boron. The other method used CVD to prepare -1-2 micron thick carbon coatings with various boron contents (0 to 15 atomic

Some symmetrical clusters of carbon andboron are discussed by introducing the new concept of conjugate polyhedra; we obtain the results that if a polyhedron of carbon (boron) is given, its conjugate polyhedron of boron (carbon) can be obtained by interchange of n and fwith 1 being kept constant, and
