Preferred Synthesis of Armchair Transition Metal Dichalcogenide Nanotubes
Abid, Luneng Zhao, Ju Huang +25
In this work, we present the synthesis of transition-metal dichalcogenide (TMDC) nanotubes with a preferred chiral angle. SnS2, MoS2, and WS2 are formed with high yield and structu…
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)…
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…
Janus MoSSe nanotubes on one-dimensional SWCNT-BNNT van der Waals heterostructures
Chunxia Yang, Qingyun Lin, Yuta Sato +10
2D Janus TMDC layers with broken mirror symmetry exhibit giant Rashba splitting and unique excitonic behavior. For their 1D counterparts, the Janus nanotubes possess curvature, whi…
Low-Temperature Synthesis of Weakly Confined Carbyne inside Single-Walled Carbon Nanotubes
Bo-Wen Zhang, Xi-Yang Qiu, Yicheng Ma +16
Carbyne, a one-dimensional (1D) carbon allotrope with alternating triple and single bonds, has the highest known mechanical strength but is unstable to bending, limiting synthesis…
