Special Issue Information

Dear Colleagues,

Owning to the ultimate limit of size, ultralow mass density, high mechanical strength, ample electronic and optic properties, nano-electromechanical systems (NEMSs) built with one- and two-dimensional materials not only acquire functionalities that are unattainable in conventional NEMSs but also serve as an ideal prober for mesoscopic physics. One crucial feature of low-dimensional NEMSs is the high sensitivity to external environments such as molecule adsorption, clamping conditions, thermal reservoir, van der Waals interaction with substrates, etc. This Special Issue aims to present experimental and theorical efforts on elucidating various factors that influence the mechanical and dynamical properties of low-dimensional NEMSs.

Topics of interest include, but are not limited to, the following:

  • Molecular dynamics modeling of low-dimensional NEMSs;
  • Novel functions of low-dimensional NEMSs;
  • Low-dimensional NEMSs associated with van der Waals interaction;
  • Effects of interlayer interactions on few-layer 2D NEMSs;
  • Effects of gas or liquid environment;
  • Effects of clamping conditions and internal stress.

Phenine nanotubes are tubular molecular structures with periodic hexatomic vacancies. The holes formed by these vacancies have a significant impact on their electrical, mechanical, and other properties. In this paper, the transverse vibration characteristics of phenine nanotubes (PNTs) are investigated by molecular dynamics (MD) simulation and continuum mechanics. A geometrically equivalent beam model is established for describing the geometric characteristics of holes. The effective static mechanical parameters of PNTs used in the proposed model are calibrated by MD simulations. The first four-order natural frequencies of PNTs are predicted by MD simulations and geometrically equivalent beam models. The results indicate that the geometrically equivalent beam model performs well in describing the transverse vibration characteristics of PNTs. Furthermore, the applicability ranges of geometrically equivalent beam models are discussed. This study offers valuable insights into the transverse vibration characteristics of porous nanostructure, which would be beneficial for the design of nanoscale mechanical resonators. Full article
