Dynamics of growing carbon nanotube interfaces probed by machine learning-enabled molecular simulations

Autor: Daniel Hedman, Ben McLean, Christophe Bichara, Shigeo Maruyama, J. Andreas Larsson, Feng Ding

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-10 (2024)

Abstract Carbon nanotubes (CNTs), hollow cylinders of carbon, hold great promise for advanced technologies, provided their structure remains uniform throughout their length. Their growth takes place at high temperatures across a tube-catalyst interfa

Publikováno v: AIP Advances, Vol 11, Iss 4, Pp 045306-045306-12 (2021)

Single-walled carbon nanotubes exist in a variety of different geometries, so-called chiralities, which define their electronic properties. Chiral selectivity has been reported in catalytic chemical vapor deposition synthesis experiments, but the und

Swinging Crystal Edge of Growing Carbon Nanotubes

Autor: Georg Daniel Förster, Vladimir Pimonov, Huy-Nam Tran, Saïd Tahir, Vincent Jourdain, Christophe Bichara

Publikováno v: ACS Nano. 17:7135-7144

Recent direct measurements of the growth kinetics of individual carbon nanotubes revealed abrupt changes in the growth rate of nanotubes maintaining the same crystal structure. These stochastic switches call into question the possibility of chirality

Chiral indices determine important properties of carbon nanotubes (CNTs). Unfortunately, their determination from high-resolution transmission electron microscopy (HRTEM) images, the most accurate method for assigning chirality, is a tedious task. We
