Migration of a Carbon Adatom on a Charged Single-Walled Carbon Nanotube
Longtao Han, Predrag Krstic, Igor Kaganovich +1
We find that negative charges on an armchair single-walled carbon nanotube (SWCNT) can significantly enhance the migration of a carbon adatom on the external surfaces of SWCNTs, al…
Collisions, magnetization, and transport coefficients in the lower solar atmosphere
J. Vranjes, P. S. Krstic
The lower solar atmosphere is an intrinsically multi-component and collisional environment with electron and proton collision frequencies in the range Hz, which ma…
ROBO: a Model and a Code for the Study of the Interstellar Medium
