Download and read online ebook Molecular Layer Deposition for Tailored Organic Thin-Film Materials write by Tetsuzo Yoshimura. This book was released on 2023-03-14. Molecular Layer Deposition for Tailored Organic Thin-Film Materials available in PDF, EPUB and Kindle. This book provides concepts and experimental demonstrations for various types of molecular layer deposition (MLD) and organic multiple quantum dots (organic MQDs), which are typical tailored organic thin-film materials. Possible applications of MLD to optical interconnects, energy conversion systems, molecular targeted drug delivery, and cancer therapy are also proposed. First, the author reviews various types of MLD processes including vapor-phase MLD, liquid-phase MLD, and selective MLD. Next, he introduces organic MQDs, which are typical tailored organic thin-film materials produced by MLD. The author then describes the design of light modulators/optical switches, predicts their performance, and discusses impacts of the organic MQDs on them. He then also discusses impacts of the organic MQDs on optical interconnects within computers and on optical switching systems. Finally, the author presents MLD applications to molecular targeted drug delivery, photodynamic therapy, and laser surgery for cancer therapy. This book is intended for researchers, engineers, and graduate students in optoelectronics, photonics, and any other field where organic thin-film materials can be applied.

Among the many atomic/molecular assembling techniques used to develop artificial materials, molecular layer deposition (MLD) continues to receive special attention as the next-generation growth technique for organic thin-film materials used in photonics and electronics. Thin-Film Organic Photonics: Molecular Layer Deposition and Applications describes how photonic/electronic properties of thin films can be improved through MLD, which enables precise control of atomic and molecular arrangements to construct a wire network that achieves "three-dimensional growth". MLD facilitates dot-by-dot—or molecule-by-molecule—growth of polymer and molecular wires, and that enhanced level of control creates numerous application possibilities. Explores the wide range of MLD applications in solar energy and optics, as well as proposed uses in biomedical photonics This book addresses the prospects for artificial materials with atomic/molecular-level tailored structures, especially those featuring MLD and conjugated polymers with multiple quantum dots (MQDs), or polymer MQDs. In particular, the author focuses on the application of artificial organic thin films to: Photonics/electronics, particularly in optical interconnects used in computers Optical switching and solar energy conversion systems Bio/ medical photonics, such as photodynamic therapy Organic photonic materials, devices, and integration processes With its clear and concise presentation, this book demonstrates exactly how MLD enables electron wavefunction control, thereby improving material performance and generating new photonic/electronic phenomena.

Download and read online ebook Molecular Engineering for Thin-film Applications write by Jie Huang. This book was released on 2014. Molecular Engineering for Thin-film Applications available in PDF, EPUB and Kindle. In this dissertation, two different approaches to employ organic molecules for thin-film applications will be discussed. One is based on modification of substrates using self-assembled monolayers (SAMs) to prevent (or enhance) nucleation of atomic layer deposition (ALD). We demonstrate area-selective deposition using electron-beam lithography (EBL) patterned octadecyltrichlorosilane (OTS) SAM as a nucleation inhibition layer followed by titanium oxide (TiO2) deposition using ALD. It was found that the e-beam dosage determined the resolution of individual line width, while the accelerating voltage dominated the minimum pitch dimension of dense line patterns achievable. Eventually, using the optimal e-beam parameters, nano-line patterns with sub-30 nm resolution and 50 nm pitch were achieved. This study offers a new approach to fabricate close-packed nano-patterns for IC devices without any challenging etching process. The other approach is direct implementation of small molecules as molecular precursors to deposit self-limiting organic multi-layers which eventually allows layer-by-layer deposition like ALD. Two types of organic molecules, 7-octenytrichlorosilane (7-OTS) and hydroquinone (HQ), were applied as backbones of these multi-layers. Conventional inorganic ALD precursors, such as trimethylaluminum (TMA) and diethylzinc (DEZ), were applied as linkers between the organic layers to form organic-inorganic hybrid thin films and nano-laminates. It was found that resulting materials characteristics can be varied from insulating to semi-conducting by altering the organic component from alkane to aromatic based molecules. This methodology provides a new route to build 2D nano-sheets with unique properties.

Precursor Chemistry of Advanced Materials available in PDF, EPUB and Kindle. Material synthesis by the transformation of organometallic compounds (precursors) by vapor deposition techniques such as chemical vapor deposition (CVD) and atomic layer deposition (ALD) has been in the forefront of modern day research and development of new materials. There exists a need for new routes for designing and synthesizing new precursors as well as the application of established molecular precursors to derive tuneable materials for technological demands. With regard to the precursor chemistry, a most detailed understanding of the mechanistic complexity of materials formation from molecular precursors is very important for further development of new processes and advanced materials. To emphasize and stimulate research in these areas, this volume comprises a selection of case studies covering various key-aspects of the interplay of precursor chemistry with the process conditions of materials formation, particularly looking at the similarities and differences of CVD, ALD and nanoparticle synthesis, e.g. colloid chemistry, involving tailored molecular precursors.
