Phys. Rev. E 68, 011506 (2003) [11 pages]Dynamics and melting of a thin confined filmReceived 5 December 2002; published 23 July 2003 Molecular dynamics is used to investigate the melting of a thin lubricant film confined between two crystalline surfaces. The dynamics of the film is significantly affected by the substrate, both in the solid and in the molten phases. The solid phase, able to sustain shear stress, shows, however, large diffusional motions of the atoms. The melting temperature depends strongly on the confinement. A phenomenological microscopic theory, based on the Lindemann criterion, is proposed to explain this effect. © 2003 The American Physical Society URL:
