Abstract
Poly(1-butene) (PB-1) films drawn from the melt have been deposited on highly oriented pyrolytic graphite (HOPG) substrates for investigation with the scanning tunneling microscope (STM). The STM investigations showed images of PB-1 flakes extending over some hundred nanometers. Their thickness was determined to be much larger than the normal tunneling distance established between the tip and a good conducting (metallic) sample surface. Close to monomolecular film steps, our STM measurements simultaneously revealed both the atomic resolution of the HOPG substrate and a superlattice showing an ordered structure pseudomorphic to the helical nature of the PB-1 macromolecule.
