Abstract The effect of defects on the melting of a two-layer dust Wigner crystal in the electrode layer of a radio-frequency gas discharge is investigated by Langevin molecular dynamics. Two types of defects have been included in the consideration: (a) point defects and dislocations and (b) particles levitating above and below a two-layer crystal (so-called strong defects). It is shown that local melting of a two-layer crystal found experimentally is explained by the occurrence of strong defects located above the crystal.
