Reduced carbon solubility in Fe nano-clusters and implications for the growth of single-walled carbon nanotubes
A. R. Harutyunyan, N. Awasthi, A. Jiang +5
Various diameters of alumina-supported Fe catalysts are used to grow single-walled carbon nanotubes (SWCNTs) with chemical vapor decomposition. We find that the reduction of the ca…
Influence of Mo on the Fe:Mo:C nano-catalyst thermodynamics for single-walled carbon nanotube growth
Stefano Curtarolo, Neha Awasthi, Wahyu Setyawan +4
We explore the role of Mo in Fe:Mo nanocatalyst thermodynamics for low-temperature chemical vapor deposition growth of single walled carbon nanotubes (SWCNTs). By using the size-pr…
Theoretical study of the thermal behavior of free and alumina-supported Fe-C nanoparticles
Aiqin Jiang, Neha Awasthi, Aleksey N. Kolmogorov +5
The thermal behavior of free and alumina-supported iron-carbon nanoparticles is investigated via molecular dynamics simulations, in which the effect of the substrate is treated wit…
The structure and stability of beta-Ta thin films
Aiqin Jiang, Trevor A. Tyson, Lisa Axe +3
Ta films with tetragonal crystalline structure (beta-phase), deposited by magnetron sputtering on different substrates (steel, silicon and silicon dioxide), have been studied. In a…
Investigation of the structure of beta-Tantalum
Aiqin Jiang, Anto Yohannan, Neme O. Nnolim +4
The local structure of beta-tantalum was investigated by comparing experimental extended x-ray absorption fine structure (EXAFS) measurements with calculated spectra of proposed mo…
