Download or read book Ultrathin Metal Transparent Electrodes for the Optoelectronics Industry written by Dhriti Sundar Ghosh and published by Springer Science & Business Media. This book was released on 2013-05-13 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transparent electrodes (TEs) are a class of materials that make it possible to bring electrical current or potentials in close proximity to optically active regions without significant loss of optical energy. However, it is a challenge to decouple the electrical and optical properties of a material, as the property of conductivity is strongly coupled to the imaginary part of the refractive index. An ideal TE has high transparency in combination with very low electrical resistivity. The main objective of the thesis was to develop TEs which can replace expensive, scarce and fragile Indium Tin Oxide (ITO), the most widely used TE material in the industry today. The thesis contains original work on ultrathin metal film (UTMF)-based TEs, which are essential elements in a wide range of optoelectronics, consumer electronics and energy devices. It presents new designs and fabrication methods and demonstrates the efficient use of UTMF-TEs in organic light emitting diodes and solar cells, achieving similar levels of efficiency to that of state-of-the-art ITO.

Book excerpt: Photonics has been the focus of an increasing ammount of resarch resources and founding since technological demands of solutions to complex problems can be solved within its scope. In this paper we will specifically focus on the demand of Transparent Conductive Materials in an specific field of photonics (i.e. opto-electronics). Particularly, we are going to fabricate and caracterize thin film stacks called DMD (i.e. Dielectric Metal Dielectric), and using simulations as a guide we will integrate this materials inside electronic devices (i.e. Silicon solar cells). The devices will use a combination Transition Metal Oxides (e.g. V2O5, MoO3) for the dielectric layers, and soft metals (Ag, Au, Al) deposited either by thermal Evaporation or Sputtering. Several ideas regarding the coalescence thickness of metallic thin films, which represents a limiting factors of this technology are tested in this work, achieving an enhancement of optical and electrical properties.

Download or read book Graphene and other Two dimensional Materials in Nanoelectronics and Optoelectronics written by Jie Sun and published by MDPI. This book was released on 2020-12-02 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphene is probably the most fascinating material discovered in this century. A group of 2D materials can be called graphene derivatives, and these have attracted tremendous interest. This includes materials that are one or a few atoms thick. They have outstanding optical/electrical properties, and, most importantly, they are flat and thin—they can be processed with existing semiconductor technologies. Therefore, they have great potential in nanoelectronics and optoelectronics, playing a revolutionary role in these fields via their integration with other bulk materials. Of course, there are still challenges, such as large-scale production, as well as the mechanical transfer of these atomically thin sheets. These are the fields where scientists are now actively doing research. In this book, some leading scientists in the area share their most recent results on the material growth, device physics/processing, and system integration of 2D materials and devices. This book can serve as a starting point for young students to get familiar with the field, and should also be valuable to established device physicists and engineers who would like to explore the potential applications of 2D materials in electronics.

Download or read book High Performance Solution Processed Transparent Electrodes for Optoelectronic Devices written by Whitney Gaynor and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Many thin-film optoelectronic devices, including displays and photovoltaic cells, require transparent conducting films as part of their device architecture. Sputtered indium tin oxide (ITO) is the most commonly used material and has high performance but is expensive and has some performance limitations, especially on flexible substrates. This dissertation presents high-performance composite transparent conducting films comprised of silver nanowires and polymer films for use as a replacement for ITO in these devices. These composites have lower sheet resistance than ITO with comparable transmission on both glass and plastic substrates and are demonstrated in this work to be compatible with high-efficiency organic photovoltaic devices. They are also more mechanically robust to ITO and show nearly substrate-independent performance. These composites have the potential to enable both low-cost photovoltaics and flexible displays.
Download or read book Novel Embedded Metal mesh Transparent Electrodes written by Arshad Khan and published by . This book was released on 2020 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents fabrication approaches that could be adapted for the high-throughput and low-cost manufacturing of the proposed transparent electrode. It proposes and demonstrates a new type of embedded metal-mesh transparent electrode (EMTE) that offers superior electrical, optical, and mechanical properties. The structure of the EMTE allows thick metal mesh to be used (for high conductivity) without sacrificing surface smoothness. In addition, the embedded structure improves the EMTE's mechanical stability under high bending stress, as well as its chemical stability in ambient environments. These design aspects are then shown to be suitable for larger electrode areas, narrower metal-mesh line widths, and a wide range of materials, and can easily be adapted to produce flexible and even stretchable devices. In closing, the book explores the practical applications of EMTEs in flexible bifacial dye-sensitized solar cells and transparent thin-film heaters, demonstrating their outstanding performance.

Download or read book Metamaterials and Metasurfaces written by Josep Canet-Ferrer and published by BoD – Books on Demand. This book was released on 2019-01-03 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metamaterials have provided applications in spectral ranges covering radio frequencies and ultraviolet. However, most applications have been extrapolated to the visible or near-infrared after being developed at the GHz level. This is due to technological reasons since fabrication of microwave antennas is not as demanding as THz resonators or plasmonic nanostructures. Accordingly, this book has been divided into three parts. In the first part, fundamentals of metamaterials and metadevices are discussed, while describing recent advances in the field. In the second part, the discussion is extended to the different spectral ranges focusing on the strategies for enabling the reconfigurability of metadevices. Given the increasing interest in THz applications, these can be found in the third part.
