“…Organic/polymeric electronic technologies have attracted considerable attention of both the academic and industrial research communities, due to their potential as a low cost, large area, solution-processable alternative to their conventional, inorganic counterparts [1,2,3,4]. In recent years, considerable interest has been shown in the development of active electronic devices such as photoconductors [5,6,7], chemiresistors [8,9] and the most popular organic thin-film field-effect transistors (OTFTs) [10,11].…”

In this work, the topic of the detrimental contact effects in organic thin-film transistors (OTFTs) is revisited. In this case, contact effects are considered as a tool to enhance the characterization procedures of OTFTs, achieving more accurate values for the fundamental parameters of the transistor threshold voltage, carrier mobility and on-off current ratio. The contact region is also seen as a fundamental part of the device which is sensitive to physical, chemical and fabrication variables. A compact model for OTFTs, which includes the effects of the contacts, and a recent proposal of an associated evolutionary parameter extraction procedure are reviewed. Both the model and the procedure are used to assess the effect of the annealing temperature on a nickel-1,4,8,11,15,18,22,25-octakis(hexyl)phthalocyanine (NiPc6)-based OTFT. A review of the importance of phthalocyanines in organic electronics is also provided. The characterization of the contact region in NiPc6 OTFTs complements the results extracted from other physical–chemical techniques such as differential scanning calorimetry or atomic force microscopy, in which the transition from crystal to columnar mesophase imposes a limit for the optimum performance of the annealed OTFTs.

In the present work, fixed Al (2.5 wt%) doped zinc oxide (ZnO) thin films are fabricated at different radio frequency (RF) power on indium doped tin oxide‐coated polyethylene terephthalate substrate by sputtering techniques. From the X‐ray diffraction (XRD) results it has been observed that all thin films have polycrystalline nature with hexagonal structure. Stress of thin film calculated from XRD measurement is increased from −0.10 × 109 to 0.23 × 109 N m−2 with increase in RF sputtering power. The morphology analyzed by field electron microscopy is observed as irregular sphere for all samples. The estimated values of thickness are 440, 870, 913, and 1086 nm for the films grown at RF sputtering powers 130, 140, 150, and 160 W, respectively. On increasing the RF power from 130 to 160 W, the optical bandgap is decreased from 3.59 to 3.48 eV. The highest conductivity obtained is 2.43 × 102 S m−1 for the sample grown at sputtering power 160 W. The study reveals that there is an impact of sputtering power on the various properties of thin films grown on flexible substrates and these films have wide applications in flexible electro‐optical applications.
