Available in PDF, EPUB and Kindle. Book excerpt: Ziel dieser Arbeit war die Herstellung und Charakterisierung eines lichtemittierenden ambipolaren organischen Feldeffekttransistors (OFET). In der Literatur wurden lichtemittierende ambipolare Feldeffekttransistoren auf der Basis organischer Moleküle, die von Interesse für neue elektro-optische Bauelemente sind, bisher noch nicht beschrieben. Für die Realisierung eines lichtemittierenden ambipolaren OFETs wurden drei verschiedenene Strategien verfolgt: Zum einen wurden konventionelle Einschichtstrukturen aufihre Elektrolumineszenzeigenschaften hin untersucht. Desweiteren wurden Zweischichtstrukturen auf der Basis eines Elektronen- und eines Löchertransportmaterials hergestellt. Schließlich wurde ein völlig neues Konzept basierend auf koverdampften, d.h. gemischten Filmen bestehend aus Löcher- und Elektronentransportmaterial, realisiert. Die Einschichtstrukturen für sich waren zwar emittierend, doch ist aufgrund der unipolaren Transporteigenschaften der organischen Materialien die Lichtemission auf einen Bereich an einem Kontakt beschränkt. Im Gegensatz dazu wurde an den Zweischichtstrukturen eine ambipolare Transportcharakteristik gemessen, jedoch keine Elektrolumineszenz beobachtet. Schließlich konnte über das neue Konzept der koverdampften Bulk-Heterostruktur erstmals Elektrolumineszenz in einem ambipolaren OFET beobachtet werden. The goal of this thesis was the fabrication and characterization of a light-emitting am- bipolar organic field-effect transistor (OFET). In the literature, light-emitting ambipolar field-effect transistors (FET) based on small molecules, which are of interest for novel electro-optical devices, have not yet been described. For the realization of such a light- emitting ambipolar OFET, three different strategies were pursued: Firstly, conventional single-layer OFETs were investigated in terms of their electroluminescent properties. Secondly, bilayer heterostructures based on an electron- and a hole-transport material were prepared. Thirdly, a novel concept based on coevaporated, i.e. mixed films consisting of an electron- and a hole-transport material, has been realized. Although the single-layer structures were light-emitting, the unipolar transport properties of the organic materials restrict light emission to a region close to one contact. In contrast, in bilayer heterostructures an ambipolar transport characteristics was measured, but no electroluminescence (EL) observed. Finally, with the novel concept of a coevaporated bulk heterostructure, EL in an ambipolar OFET could be observed for the first time.
Download or read book Electrical Characterization of Organic Electronic Materials and Devices written by Professor Peter Stallinga and published by John Wiley & Sons. This book was released on 2009-10-08 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Think like an electron Organic electronic materials have many applications and potential in low-cost electronics such as electronic barcodes and in light emitting devices, due to their easily tailored properties. While the chemical aspects and characterization have been widely studied, characterization of the electrical properties has been neglected, and classic textbook modeling has been applied. This is most striking in the analysis of thin-film transistors (TFTs) using thick “bulk” transistor (MOS-FET) descriptions. At first glance the TFTs appear to behave as regular MOS-FETs. However, upon closer examination it is clear that TFTs are unique and merit their own model. Understanding and interpreting measurements of organic devices, which are often seen as black-box measurements, is critical to developing better devices and this, therefore, has to be done with care. Electrical Characterization of Organic Electronic Materials and Devices Gives new insights into the electronic properties and measurement techniques for low-mobility electronic devices Characterizes the thin-film transistor using its own model Links the phenomena seen in different device structures and different measurement techniques Presents clearly both how to perform electrical measurements of organic and low-mobility materials and how to extract important information from these measurements Provides a much-needed theoretical foundation for organic electronics

Download or read book Introduction to Thin Film Transistors written by S.D. Brotherton and published by Springer Science & Business Media. This book was released on 2013-04-16 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Thin Film Transistors reviews the operation, application and technology of the main classes of thin film transistor (TFT) of current interest for large area electronics. The TFT materials covered include hydrogenated amorphous silicon (a-Si:H), poly-crystalline silicon (poly-Si), transparent amorphous oxide semiconductors (AOS), and organic semiconductors. The large scale manufacturing of a-Si:H TFTs forms the basis of the active matrix flat panel display industry. Poly-Si TFTs facilitate the integration of electronic circuits into portable active matrix liquid crystal displays, and are increasingly used in active matrix organic light emitting diode (AMOLED) displays for smart phones. The recently developed AOS TFTs are seen as an alternative option to poly-Si and a-Si:H for AMOLED TV and large AMLCD TV applications, respectively. The organic TFTs are regarded as a cost effective route into flexible electronics. As well as treating the highly divergent preparation and properties of these materials, the physics of the devices fabricated from them is also covered, with emphasis on performance features such as carrier mobility limitations, leakage currents and instability mechanisms. The thin film transistors implemented with these materials are the conventional, insulated gate field effect transistors, and a further chapter describes a new thin film transistor structure: the source gated transistor, SGT. The driving force behind much of the development of TFTs has been their application to AMLCDs, and there is a chapter dealing with the operation of these displays, as well as of AMOLED and electrophoretic displays. A discussion of TFT and pixel layout issues is also included. For students and new-comers to the field, introductory chapters deal with basic semiconductor surface physics, and with classical MOSFET operation. These topics are handled analytically, so that the underlying device physics is clearly revealed. These treatments are then used as a reference point, from which the impact of additional band-gap states on TFT behaviour can be readily appreciated. This reference book, covering all the major TFT technologies, will be of interest to a wide range of scientists and engineers in the large area electronics industry. It will also be a broad introduction for research students and other scientists entering the field, as well as providing an accessible and comprehensive overview for undergraduate and postgraduate teaching programmes.
