Abstract
1D van der Waals heterostructures (1D vdWH) were recently reported to be successfully synthesized. We perform molecular dynamics simulations to investigate the buckling behavior of a 1D vdWH composed of inner carbon nanotube, a middle boron nitride nanotube and an outer molybdenum disulfide nanotube. We find that as the temperature increases, the 1D vdWH gradully loses its stability and the peak value of compressive stress decreases. Slenderness ratio have a slight influence on the strength and stability of 1D vdWH under axial compression.
