Pentacene nanostructures on surface-hydrophobicity-controlled Polymer/SiO2 bilayer gate-dielectrics

New evidence of a pentacene bulk phase, which shows a different layer orientation from the thin-film phase, was discovered. Thin films prepared on surface-hydrophobicity-controlled polymer/SiO2 dielectrics, were studied by using 2D grazing-incidence X-ray diffraction.
