论文摘要
据报道,一维范德华异质结构(1D VDWH)已成功合成。我们执行分子动力学模拟,以研究由内碳纳米管,中硼纳米管和二硫化钼纳米管组成的1D VDWH的屈曲行为。我们发现,随着温度的升高,1D VDWH逐渐失去其稳定性,压缩应力的峰值降低。在轴向压缩下,细长比对1D VDWH的强度和稳定性有略有影响。
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.
