Asperity contacts at the nanoscale: comparison of Ru and Au
We employ molecular dynamics simulations to bring two surfaces together; one flat and the other with a single asperity.
Asperity contacts at the nanoscale: comparison of Ru and Au
We compare the process of asperity contact formation and breaking in Au and Ru, two materials currently in use in micro electro mechanical system switches.
Asperity contacts at the nanoscale: comparison of Ru and Au
Molecular dynamics (MD) simulation is a powerful tool for studying adhesion, defect formation and deformation on the nano-scale level (that of asperities in MEMS contacts).
Asperity contacts at the nanoscale: comparison of Ru and Au
We implement this potential in our molecular dynamics simulations of asperity contact and separation.
