Abstract Most electronic devices made of organic materials are fabricated using a thin film as a signal transducer element, whose structuring (supramolecular arrangement), in addition to the physical and chemical characteristics of the material itself, is a fundamental factor in the optical and electrical properties of the film and respective device. In this project thin films (nanometers thick) of dinaphtho[2,3-b:2',3'-f]thieno[3,2-b]thiophene (DNTT) will be fabricated. The films will be produced using Physical Vapor Deposition (PVD) and Langmuir-Schaefer (LS) techniques. The main objectives of the project are: i) determine the supramolecular arrangement of DNTT PVD and LS films, which implies monitoring growth, verifying the formation of aggregates, or not, in the films, molecular organization, surface morphology on micro and nanometric scales and crystallinity; ii) fabricate electrolyte-dependent organic field effect transistors (EGOFETs) and Schottky diodes from DNTT PVD and LS films; and iii) investigate the influence of the supramolecular arrangement of these films on electrical properties, especially mobility in different directions (horizontal and vertical). Thus, it seeks to relate such mobility to the supramolecular arrangement and to the organic electrode-film interface. This project is part of the Thematic National Institute of Science and Technology (INCT) in Organic Electronics (INEO), 2014/50869-6, and will be developed under the supervision of Prof. Dr. Neri Alves. In addition, it provides for a BEPE internship to be held at Bangor University under the supervision of Prof. Dr. Jeff Kettley. (AU) | |
