The stability and electronic properties of composite B{sub x}C{sub y}N{sub z}nanotube heterojunctions were studied using both ab initio and semi-empirical approaches. C/BN and BC{sub 2}N/BN superlattices or isolated junctions were investigated as specific examples of the wide variety of electronic devices that can be realized using such nanotubes. The characteristics of these junctions are predicted to be largely independent of the radius, helicity, multiplicity, or degree of perfection of the constituting nanotubes. {copyright} {ital 1997 American Institute of Physics.}
