Motivated by a recent computer simulation of the commensurate-incommensurate transition of monolayer krypton on graphite, a theoretical model for the weakly incommensurate phase at finite temperatures is presented. The phonon spectrum of the adsorbed layer and the width of the incommensurate domain walls are calculated selfconsistently. Results for the wall-width are shown to be in good agreement with the findings of the computer simulations.
