Reentrant melting in solid films with quenched random impurities

Crystalline films with a quenched distribution of impurities are studied. These materials are stable only over a finite band of temperatures. At sufficiently low temperatures, thermally excited dislocation pairs are broken apart by the random impurity potential. The hexatic phase which results can p...
