TL;DR: In this article, the effects of the polar functional groups and rough topography of the gate dielectric layer on the characteristics of pentacene field effect transistors were analyzed. But the authors did not consider the effect of the number of polar groups.

TL;DR: In this paper, a profile is created using a single layer of photoresist, defining the regions where the organic semiconductor is to be deposited, and the resulting transistor characteristics have an off current that is systematically below 1pA.
Abstract: We have developed a simple and efficient method for patterning small molecule semiconductors for applications in the field of organic electronics. In our approach, a profile is created using a single layer of photoresist, defining the regions where the organic semiconductor is to be deposited. Subsequent deposition of a small molecule semiconductor results in a discontinuity of the semiconductor film at the photoresist edge. The resulting transistor characteristics have an off current that is systematically below 1pA. We demonstrate both p-type and n-type organic thin-film transistors using this method, using pentacene and copper hexadecafluorophthalocyanine (F16CuPc), respectively.

TL;DR: It is shown that the cell explores the surface with a deformation of the membrane whose minimum curvature radius is 90 (+/- 45) nm, which leads to a progressive decrease of the pentacene local radius of curvature and hence to the surface area accessible to the cell.

TL;DR: In this article, angle resolved photoemission spectroscopy using a uniaxially aligned crystalline thin film was used to measure the intermolecular and intramolecular dispersions of pentacene.
Abstract: The intermolecular and intramolecular dispersions of pentacene are measured by angle resolved photoemission spectroscopy using a uniaxially aligned crystalline thin film. The band structure perpendicular to the molecules displays a small dispersion in agreement with density functional theory (DFT). Parallel to the molecules, two $\ensuremath{\pi}$ bands consisting of five and six orbitals are clearly observed. In these intramolecular bands, the orbital emissions are shown to be in agreement with calculations of the photoemission intensities based on DFT both in terms of position and width in momentum space.
