چکیده

The physical and structural characteristics of pentacene thin films on indium tin oxide (ITO)-coated glass were studied. deposited using the thermal evaporation method with deposition times 20, 30, 60 minutes. Field-emission scanning electron microscopy (FESEM) images revealed that film thickness increased time, a bulk phase layer appearing at presence thin-film corresponding to 15.5 Å lattice spacing was demonstrated by X-ray diffraction (XRD) patterns in 20 30 Meanwhile, time minutes 14.5 Å, existence verified film. Atomic force (AFM) crystallinity ITO-coated exhibited formation similar islands modular grains, results fine crystalline structure. From current-voltage (I-V) current density-voltage (J-V) characteristics, ohmic as pentacene’s decreased. Pentacene an substrate showed potential development broadband narrowband optoelectronic devices transparent substrate.

Structural and Electrical Properties of Polymorphic Pentacene Thin Films

Due to its outstanding carrier transport capabilities the aromatic hydrocarbon pentacene is still one of the most promising out of all organic semiconducting materials investigated so far. Pentacene appears in several polymorphic structures that significantly differ with respect to the d(001) spacing. It is shown, that precise control of the epitaxial growth process of thin films enables not on...

Structural, Electrical and Optical Properties of Molybdenum Oxide Thin Films Prepared by Post-annealing of Mo Thin Films

Molybdenum thin films with 50 and 150 nm thicknesses were deposited on silicon substrates, using DC magnetron sputtering system, then post-annealed at different temperatures (200, 325, 450, 575 and 700°C) with flow oxygen at 200 sccm (standard Cubic centimeter per minute). The crystallographic structure of the films was obtained by means of x-ray diffraction (XRD) analysis. An atomic force micr...
