“…These interests stimulated a search for a better understanding of the researchers, with respect to the interaction of molecules in liquid subphases; and how the manipulation of these materials as conductive polymers can have their optical and electrical properties optimized and possibly applied in organic devices, such as: diodes, photodetectors or organic photovoltaic devices. Despite the vast theory and knowledge in the field of inorganic materials, there is still much to be discovered in relation to the processing of organic materials [11].…”

Low-bandgap organic polymers, poly[(4,4 bis(2 ethylhexyl)cyclopenta [2,1 b:3,4 b′]dithiophene) 2,6 diyl al (2,1,3 benzothiadiazole) 4,7 diyl](PCPDTBT), and poly [(4,4′ dioctyldithieno[3,2 b:2′,3′d] silol 2,6 diyl) alt (2,1,3 benzothiadiazole) 4,7 diyl)], (Si-PCPDTBT) were analyzed at the air-water interface forming a Langmuir monolayer. In order to form stable monolayers and to transfer to solid supports, amphiphilic molecules of stearic acid (SA) were mixed with them. For the pristine polymers, the floating monolayers were transferred onto solid substrates via the Langmuir-Schaefer (LS) technique. Surface pressure-area isotherms and compressibility modulus curves demonstrated that the SA incorporation to the polymers at the air-water interface modified the rheological properties of the Langmuir films, since the films became less compressible at higher pressures and there is clear conformational reorganization taking place at intermediary pressures. The UV-Vis absorption also depicted the changes on the overall film morphology by the shift on the maximum absorption bands, and along with cyclic voltammetry curves the absorption spectra made it possible to estimate the energy diagrams for the polymers. Photoconductivity effects were observed for all the sample, among which the pristine polymers fabricated by LS showed better results, suggesting that the organization provided by the Langmuir-Blodgett (LB) technique was not enough to overcome the insulating characteristic of the SA molecules in this specific configuration.

“…To reach high rectification ratios, a high Schottky barrier is needed. For the cathode, low-work-function metals such as aluminum are preferable but they suffer from oxidation, which results in a voltage offset in the diode forward characteristics . Copper does not suffer from oxidation to the same extent as aluminum but has a higher work function and therefore diodes with copper cathodes should exhibit a lower rectification ratio.…”

Printed, organic diodes with a thin organic interfacial layer forming a Schottky barrier were fabricated and characterized. Experiments indicated that the thickness of the barrier layer is <10 nm. The interfacial layer reduces the reverse current of the diode by 2 orders of magnitude without significantly affecting the forward characteristics above 1 V. As a result, printed organic diodes with a rectification ratio of 5 orders of magnitude were fabricated. The diodes enable applications where low reverse currents are needed.

“…Schottky diodes based on electrospun PAni nanofibers with thicker diameters possess clear rectification behavior, whereas decreasing the diameter of fibers significantly reduces the rectification ratio [106]. The electrical characteristics of these devices based on polymers are often affected by the doping process [90], [107], [108]. Dopant type has an influence on the Fermi level of the semiconductive polymer and hence affects the rectifying behavior of the Schottky junction device [109].…”

Polymeric materials are emerging as an important component for organic electronics due to their combined features of soft materials and organic semiconductor/conductor. Different from solid-state bulk materials, polymers are synthesized and modulated with a facile method, with their controllable properties. Therefore, polymers have been recently used in Schottky junction devices that demonstrate features of enhanced performances, flexibility, and easy processing. Polymer-based Schottky junctions have drawn a lot of interest in several prototype applications like photodetectors, energy harvesters, and gas sensors. With this review, we summarize recent progress in synthesis and modulation of polymers and fabrication of polymer-based Schottky junction devices. Designs of applications of sensory devices like photodetectors, energy harvesters, and gas sensors are also presented.
