Structures of iron and cobalt bimetallic clusters for optimized chemical vapor deposition growth of single-walled carbon nanotubes
Qingmei Hu, Daniel Hedman, Ya Feng +17
We investigate iron-cobalt (Fe-Co) alloys as a representative high-performance catalyst system for SWCNT growth in a systematic manner by combining chemical vapor deposition (CVD)…
Machine-Learned Bond-Order Potential for Exploring the Configuration Space of Carbon
Ikuma Kohata, Kaoru Hisama, Keigo Otsuka +1
Construction of transferable machine-learning interatomic potentials with a minimal number of parameters is important for their general applicability. Here, we present a machine-le…
Analysis of Fe and Co binary catalysts in chemical vapor deposition growth of single-walled carbon nanotubes
Qingmei Hu, Ya Feng, Wanyu Dai +17
Metal catalysts play a pivotal role in the growth of single-walled carbon nanotubes (SWCNTs), with binary metallic catalysts emerging as an efficient SWCNT synthesis strategy. Amon…
Metallic NbS2 one-dimensional van der Waals heterostructures
Wanyu Dai, Yongjia Zheng, Akihito Kumamoto +12
This study presents the experimental realization of metallic NbS2-based one-dimensional van der Waals heterostructures applying a modified NaCl-assisted chemical vapor deposition a…
Catalyst-mediated etching of carbon nanotubes exhibiting electronic-structure insensitivity and reciprocal kinetics with growth
K. Otsuka, S. Maruyama
The selective etching of carbon nanotubes has been widely explored as a post-synthetic route for enriching semiconducting species. As nanoelectronic applications increasingly deman…
