In this work, we calculated the phonon dispersion of GaNNTs (4,0) and (4,4) by quantum ESPRESSO package using Density Functional Theory (DFT), pseudo potentials, and plane wave self-consistent field (PWscf) method. For the purpose of lattice-dynamical calculation and phononic properties, we used PWscf and Phonon codes. The former produces the self-consistent electronic and all related computati...

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

The aims of this project are to investigate the effects of Isoniazid drug adsorption on the geometrical and electrical structure of pristine and Ni-doped Gallium nitride nanotube (GaNNTs). For this purpose, 24  different configuration models are considered  for adsorbing Isoniazid on the surface of nanotube and then all considered structures are optimized by using density function theory (DFT) ...
