Future perspectives.Full-text restricted to subscribers or individual document purchasers.This book provides an overview of magnetic resonance in organic semiconductor devices, including a framework of the underlying spin physics. It starts with an introduction of organic electronic and optoelectronic devices. Basic principles of optical and electrical detection are included, as well as the conventional microwave detection of electron paramagnetic resonance (EPR) for organic devices. The details of a magnetic resonance spectrometer are presented as well as operando conditions (measurements under real working conditions). The details for experimental setup are provided. This book will also include emerging research in the field of organic neuromorphic devices, and aims to offer essential knowledge for researchers, developers, and students interested in applying magnetic resonance methods to electronic and optoelectronic devices. Part of IOP Series in Advances in Optics, Photonics and Optoelectronics.Researchers in the field of organic semiconductors.Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.Naoki Asakawa is serving as Principal Investigator at the Emergent Polymer Science Laboratory, Gunma University, Japan. He earned his Bachelor Engineering degree from the Department of Polymer Chemistry, Tokyo Institute of Technology (Tokyo Tech) in 1991, followed by his Master of Engineering degree in 1993 and Doctoral degree in 1996 under the supervision of Prof. Isao Ando, also from the Department of Polymer Chemistry, Tokyo Tech. During his doctoral studies, he conducted research at the Chemistry Department, Washington University in St. Louis (1993-1994) as a Visiting Scholar under the super- vision of Professor Jacob Schaefer. He began his academic career as an Assistant Professor in the Department of Biomolecular Engineering, Tokyo Tech (1994-2006). Subsequently, he was appointed as Designated Associate Professor at the Institute of Scientific and Industrial Research (ISIR), Osaka University (2006-2009) as a collaborator with Profs. Yasushi Hotta, Teruo Kanki, Hitoshi Tabata and Tomoji Kawai. He then served as Associate Professor and Principal Investigator in the Department of Chemistry and Chemical Biology, Graduate School of Engineering, Gunma University (2009-2019) before becoming a Full Professor in the Molecular Science Division, Graduate School of Science and Technology, Gunma University, Japan (2019-present). His research interests encompass the development of bioinspired neuromorphic organic electronic devices using molecular dynamics. Additionally, he is dedicated to advancing and applying non-invasive characterization techniques utilizing magnetic resonance spectroscopy for these devices.
