Gan Nanotubes

摘要

We perform parametrized density-functionalcalculations to predict the stability and formation mechanismof GaN nanotubes. Strain energies of GaN nanotubes arecomparable to those of carbon nanotubes, suggesting thepossibility for the formation of GaN nanotubes. We note thatan intermediate phase with (4,6,10) polygons exist at armchairtube edge, which may play as a nucleation seed of further tube growth.
