“…AlN nanotubes with diameters of 30-80 nm have been successfully synthesized via direct nitriding of aluminum powder [14][15][16], theoretical calculations on single-walled AlN nanotubes have indicated that these tubular structures are stable and have unique electronic properties [17][18][19]. AlN nanotubes have been extensively investigated over the past years, to the best of our knowledge, there are few first principle simulations about the elastic properties by a consideration of AlN nanotubes with different sizes and structures.…”

“…Tondare et al successfully synthesized the AlNNTs with diameter ranging from 30-80 nm [14]. Recently, the other papers have been reported on the synthesis of AlNNTs through different methods [15,16]. Recently, Lim and Lin have reported an ab initio study of the hydrogen chemisorption on singlewalled AlN nanotubes, showing that the calculated energy barrier and the energy of reaction is about 0.89 and -0.11 eV, respectively [4].…”

The thermodynamic and kinetic feasibility of H(2) dissociation on the BN, AlN, BP and AlP zigzag nanotubes has been investigated theoretically by calculating the dissociation and activation energies. We determined the BN and AlP tubes to be inert toward H(2) dissociation, both thermodynamically and kinetically. The reactions are endothermic by 5.8 and 3 kcal mol(-1), exhibiting high activation energies of 38.8 and 30.6 kcal mol(-1), respectively. Our results indicated that H(2) dissociation is thermodynamically favorable on both PB and AlN nanotubes. However, in spite of the thermodynamic feasibility of H(2) dissociation on PB types, this process is kinetically unfavorable due to partly high activation energy. Generally, we concluded that among the four studied tubes, the AlN nanotube may be an appropriate model for H(2) dissociation process, from a thermodynamic and kinetic stand point. We also indicated that H(2) dissociation is not homolytic, rather it takes place via a heterolytic bond cleavage. In addition, a comparative study has been performed on the electrical and geometrical properties of the tubes. Our analysis showed that the electrical conductivity of tubes is as follows: BP>AlP>BN>AlN depending on how to combine the electron rich and electron poor atoms.

Our main objectives are to address the following fundamental issues: (1) A density functional theory study on the structural and electronic properties of the zigzag singlewalled aluminum nitride nanotubes (AlNNTs) with various diameters, using B3LYP/6-31G* level of theory.(2) An ONIOM study on the curvature effect of AlNNTs on the NH 3 adsorption process using B3LYP/6-31G* and semiempirical AM1 approaches. Furthermore, a potential energy surface is calculated for NH 3 moving toward AlNNT surface. In contrast to semiconducting carbon nanotubes (Louie, Top Appl Phys 80:113, 2001) our calculations confirmed that the HOMO-LUMO energy gap of AlNNTs increases with an increase of the tube diameter. Additionally, we showed that HOMO/LUMO interaction between NH 3 and AlNNTs becomes stronger as the tube diameter decreases.
