Electrostatic charge distribution in armchair and zigzag carbon nanotubes: a numerical comparison of CNT charge models

Abstract In engineering—especially in mechanics, lightweight engineering, aerospace electrical engineering as well bioengineering—there is a desire of developing materials enabling an excellent performance with respect to mechanical, thermal, and properties. One the most promising are carbon nanotubes (CNTs), they show mechanical To improve understanding behavior, i.e., charge distribution single-walled nanotubes, both open ended armchair zigzag types investigated. present research, three different modeling approaches, classic electrostatic model, model by Li Chou Mayer, analyzed compared their further applicability. numerical investigations, test cases performed: (i) charged overall charge, (ii) CNTs exposed external electric field, (iii) combined. Furthermore, influence geometric parameters It shown that applied distributes over whole CNT having maxima at ends tubes. These can be influenced both, field strength.
