Abstract
In the frame of the one-dimensional elastically hinged molecule (EHM) model of crystal the thermally activated motion of a rather wide domai n wall (DW) was studied by numerical simulation at temperatures much h igher than Peierls-Nabarro barrier but much lower than kink-pair nucle ation temperature. It was found that DW undergo Brownian-like motion a nd at some moments the drift velocity of DW can be changed by obtainin g (losing) some energy from (to) thermal fluctuations.
