Structural evolution of perfluoro-pentacene films on Ag(111): transition from 2D to 3D growth.
The structural evolution and thermal stability of perfluoro-pentacene (PF-PEN) thin films on Ag(111) have been studied by means of low-temperature scanning tunnelling microscopy (STM), low-energy electron diffraction (LEED), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), and thermal desorption spectroscopy (TDS). Well-defined monolayer films can be prepared by utilizing ...
متن کاملStructural characterization of a pentacene monolayer on an amorphous SiO2 substrate with grazing incidence x-ray diffraction.
Grazing incidence X-ray diffraction reveals that a pentacene monolayer, grown on an amorphous SiO2 substrate that is commonly used as a dielectric layer in organic thin film transistors (OTFTs), is crystalline. A preliminary energy-minimized model of the monolayer, based on the GIXD data, reveals that the pentacene molecules adopt a herringbone arrangement with their long axes tilted slightly f...
متن کاملPhotoinduced interfacial charging and "explosion" of monolayer pentacene islands.
Electrostatic force microscopy shows that the electric field gradients above pentacene monolayer islands on 2-nm SiO2/Si substrates, in a dark, dry nitrogen environment, display a wide distribution of signs and magnitude that is dependent on sample history. Under 12 mW/cm2 green (532 nm) illumination, pentacene islands accumulate positive charge because of photoexcited electron transfer across ...
متن کاملCompression-Induced Structural Transition in a Self-Assembled Monolayer
Molecular dynamics simulations are used to probe the atomic-scale behavior of a model for a selfassembled monolayer of n-hexadecanethiol chemisorbed on a gold (111) surface compressed under high loads. These simulations suggest that SAMs may undergo abrupt rearrangements during compression that retain efficient packings of the chains. These changes may in turn modify the elastic properties of t...
متن کاملChannel formation in single-monolayer pentacene thin film transistors
The geometrical arrangement of single-molecule-high islands and the contact between them have large roles in determining the electrical properties of field effect transistors (FETs) based on monolayer-scale pentacene thin films. As the pentacene coverage increases through the submonolayer regime there is a percolation transition where islands come into contact and a simultaneous rapid onset of ...
