Substrate defects and commensurate-incommensurate phase transition in adsorbed films
Lyuksyutov I. F.
The soliton density index is calculated near the point of the transition from a commensurate phase to an incommensurate phase in adsorbed films in the presence of a random arrangement of point defects in the substrate. This index is 5/6 and very different from that (1/2) of an ideal substrate.
