X-ray diffraction measurements on thin films of poly(hexyl-pentylsilane) cast on silicon substrates are presented. The polymer chains pack in a hexagonal lattice which is oriented such that the chains lie parallel to the surface. In addition, a remar

Grazing incidence x-ray diffraction has been used to characterize the near surface structure of an aromatic polyimide film. It is shown that within the first 90 A from the surface the ordering of the polymer molecules is markedly enhanced. As the pen
