Electronic structure of nanocones of boron nitrite
Sergio Azevedo, Mario S. C. Mazzoni, H. Chacham +1
We apply first-principles calculations to study the electronic structure of boron nitride nanocones with disclinations of different angles . Nanocones with odd values of $n…
A stacking-fault based microscopic model for platelets in diamond
C. R. Miranda, R. W. Nunes, A. Antonelli
We propose a new microscopic model for the planar defects in diamond commonly called platelets. This model is based on the formation of a metastable stacking fault, which…
Stability of antiphase line defects in nanometer-sized boron-nitride cones
Sergio Azevedo, Mario S. C. Mazzoni, Ricardo W. Nunes +1
We investigate the stability of boron nitride conical sheets of nanometer size, using first-principles calculations. Our results indicate that cones with an antiphase boundary (a l…
