摘要：
The dynamics of one-dimensional finite discrete sine-Gordon (Frenkel-Kontorova) chains is studied for small values of misfit. It is shown that nonintegrability leads to kink trapping at the system surface, stopping the system motion as a whole and localizing energy at the system boundary. An interpretation from the point of view of both dislocation dynamics and proton transport is proposed.
