THE MOLECULAR-STRUCTURE OF A DODECANOL GRAPHITE INTERFACE DEFECTS SHOWN BY STM - IMAGING OF PURE 1-DODECANOL AND 1-DODECANOL-1,8-OCTANEDIOLADSORBED LAYERS

The STM observation of a dodecanol layer adsorbed on graphite has reve aled a large amount of boundary defects between lamellae. A careful an alysis of STM views showed the equivalency of defects, but a screening of tunnelling parameters was not able to determine whether irregular junctions are between methyl or hydroxyl termini of molecules. The obs ervation of a mixed layer of coadsorbed dodecanol and octanediol showe d the difference between molecular bounds, so the structure of defects was revealed.
