Phase separation of a C 60-C 70 binary mixture at 1:1 composition on Cu(111) surface was studied after quenching from a 2D fluid temperature. Because of the shape difference, C 70 molecules were imaged differently from C 60 in STM images. Highly non-linear and irreversible phenomena due to late stage growth were observed, revealing a time dependent order parameter. The correlation function and its 2D Fourier transform were calculated for annealing times at 400°C. Time dependence of the structure factor was calculated.
