BREWSTER-ANGLE MICROSCOPY OF FULLERENE MONOLAYERS

The aim of this paper is to present a direct observation by means of B rewster angle microscopy of Langmuir films made of C-60 along the proc ess of their compression We found coexistence of a gas and a condensed phase at low area densities. Our results agree with the formation of multilayers even at low area densities. We made compressions of the fi lms at several speeds, with rapid compressions we found that the conde nsed phase formed foam-like structures and circular domains of differe nt sizes at very small area densities.
