The explicit form of the colloidal particle interaction has been calculated in restricted colloidal systems. Based upon the exact interaction, effects of buckling of the monolayer of colloidal particles in the middle of the electrolyte film is considered and the melting condition of colloidal crystals is found. Thermal fluctuations of inner degrees of freedom of the edge dislocation are shown to affect the condition of the dislocation-mediated melting. (c) 1995 The American Physical Society
