We report the results of thermal and structural studies near the -C–-I critical point in free-standing thin films of . The profiles of the -C–-I heat-capacity anomalies are found to exhibit an unexpected crossover behavior with film thickness in reduced dimensions, which is qualitatively similar to that seen in by Yao et al. in the bulk. Moreover, we observe the existence of a surface hexatic -L phase in films of less than eight layers whose phase sequence is, however, dramatically different from that observed in thicker films.
