Available in PDF, EPUB and Kindle. Book excerpt: Organic light emitting diodes (OLEDs) have attracted a wide spread interest due to their potential applications in multicolor flat panel displays. OLEDs are essentially one or several organic thin film semiconductors sandwiched between two electrodes. The charge carrier injection efficiency of OLEDs is affected by the energy barrier height at the interfaces between thin layers in the device. Indium tin oxide (ITO) is used as the anode for injection of holes into highest occupied molecular orbitals (HOMO) of the organic semiconductors in OLEDs. This thesis deals mainly with surface modification of ITO. By surface modification, the work function of ITO could be increased, and hence the energy barrier between Fermi level of the anode and HOMO of the organic semiconductor is decreased. Accordingly, the drive voltage of OLEDs could be reduced. ITO surfaces were modified by oxygen, ammonia, and argon plasma respectively. X-ray photoelectron spectroscopy (XPS) has been used to characterize these surfaces. A surface band-bending model is proposed based on the XPS information. This band model successfully explains the change in work function of ITO after plasma treatment. Hydrogenated amorphous carbon (a-C:H) films deposited by ethylene plasma under various conditions were also studied in this thesis. The distribution of 'sp'3 and 'sp'2 bonding in these films was investigated using XPS and x-ray absorption near-edge spectroscopy (XANES). The factors affecting the structure of the a-C:H films are discussed.

Book excerpt: Indium tin oxide serve a critical function in many organic devices, such as organic light emitting diodes and organic photovoltaics. To optimize the performances of these devices, it is desirable to tune the interface between the indium tin oxide and the next functional layer of these devices. A common surface modification of transparent conductive oxides is through the use of self-assembled monolayers. This methodology enables a simultaneously tuning of the properties and performance of this interface, including the surface energy, work function and durability of the transparent conductive oxide. Phosphonic acid and silane based monolayers have been extensively studied and used in devices for their ability to tune the interfacial properties of transparent conductive oxide. Herein, alcohol based monolayers are first demonstrated on transparent conductive oxide surfaces. The electrochemical and chemical stabilities of alcohol based monolayers, as well as changes in the optical properties of the Indium tin oxide as a function of their stability were evaluated in comparison to more traditional routes of surface modification, such as through the use of silanes and phosphonic acid based monolayers. The tunability of both work function and surface energy of the modified Indium tin oxide were also determined for assessing their electronic properties.

Download or read book Modification of Indium-Tin Oxide Surfaces: Enhancement of Solution Electron Transfer Rates and Efficiencies of Organic Thin-Layer Devices written by Chet Carter and published by . This book was released on 2006 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation has focused on the study of the ITO/organic heterojunction and the chemistries therein, it proposes appropriate strategies that enhance the interfacial physical and electronic properties for charge injection with application to organic thin-layer devices. We focused on four major aspects of this work: i) To characterize the ITO surface and chemistries that may be pertinent to interaction with adjacent organic layers in a device configuration. This developed a working model of surface and provided a foundation for modification strategies. Characterization of the electronic properties of the surface indicate less than 5% of the geometrical surface is responsible for the bulk of current flow while the rest is electrically inactive. ii) To determine the extent to which these chemistries are variable and propose circumstances where compositional changes can occur. It is shown that the surface chemistry of ITO is heterogeneous and possible very dynamic with respect to the surrounding environment. iii) To propose a strategy for modification of the interface. Modification of ITO surfaces by small molecules containing carboxylic acid functionalities is investigated. Enhancements in the electron transfer rate coefficient were realized after modification of the ITO electrode. The enhancements are found to stem from a light etching mechanism. Additionally, an elecro-catalytic effect was observed with some of the modifiers. iv) Apply these modifications to organic light emitting diodes (OLEDs) and organic photovoltaic devices (OPVs). Enhancements seen in solution electrochemical experiments are indicative of the enhancements seen for solid state devices. Modifications resulted in substantially lower leakage currents (3 orders of magnitude in some cases) as well as nearly doubling the efficiency. An additional chapter describesthe creation and characterization of electrochemically grown polymer nano-structures based on blazed angle diffraction gratings. The discussion details the micro-contact printing process and the electro-catalytic growth of the conductive polymers PANI and PEDOT to form diffraction grating structures in their own right. The resulting diffraction efficiency of these structures is shown to be sensitive to environmental conditions outlining possible uses as chemical sensors. This is demonstrated by utilizing these structures as working pH and potentiometric sensors based on the changing diffraction efficiency.

This book was released on 2008-11-13 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Patterning or lithography is at the core of modern science and technology and cuts across all disciplines. With the emergence of nanotechnology, conventional methods based on electron beam lithography and extreme ultraviolet photolithography have become prohibitively expensive. As a result, a number of simple and unconventional methods have been introduced, beginning first with research demonstrations in the mid 1990s. This book focuses on these unconventional patterning techniques and their applications to optics, organic devices, electronic devices, biological devices, and fluidics.
