For many years, it has been a significant concern for nanoscience researchers to synthesize nanomachines with steerable motion. Despite the notable number of studies on the motion of nanocars on a surface, the motion characteristics of carbon nanotubes received less attention. Remarkable features such as symmetry, strength, and stiffness made carbon nanotubes (CNTs) a proper option as wheels in the nanocars. In this paper, for the first time, the motion of carbon nanotube on a gold substrate and its advantages over previous wheels such as fullerene and p-carborane are investigated. We demonstrate that contrary to the other wheels, CNT moves in a directed path, making them an ideal option as...
