Article Synopsis
- The study focuses on the motion of surface-rolling nanomachines, which have potential applications in nanotransportation systems by carrying molecular payloads on surfaces.
- Using molecular dynamics simulations, researchers observed that carbon-based nanovehicles face higher energy barriers and lower movement efficiency on silicene compared to other materials like graphene.
- They introduced a nanoroad structure to limit the motion of these nanomachines and found that applying a thermal gradient helps direct their movement towards lower energy regions for better controllability.
With the synthesis of nanocar structures the idea of transporting energy and payloads on the surface became closer to reality. To eliminate the concern of diffusive surface motion of nanocars, in this study, we evaluate the motion of C and C-based nanovehicles on graphene and hexagonal boron-nitride (BN) surfaces using molecular dynamics simulations and potential energy analysis. Utilizing the graphene-hBN hybrid substrate, it has been indicated that C is more stable on boron-nitride impurity regions in the hybrid substrate and an energy barrier restricts the motion to the boron-nitride impurity.
