Unique reference on the fundamentals, applications, and latest research in electroluminescence of organic molecules Organic Electroluminescence provides a comprehensive overview of organic electroluminescent materials from their structure-property relationships to the outlook of improved device performance. Divided into three parts, the first section of the book covers fundamental aspects of OLEDs such as history, structures, properties, and operating and aging mechanisms. The second section provides quantum chemical and experimental insights into correlations between device performance, material characteristics, molecular physical parameters, and molecular structure. The last section is devoted to improving device performance in real world applications using molecular and device simulations. Featuring contributions from experts from around the world, Organic Electroluminescence discusses sample topics including: Fundamental concepts in the fields of display, organic electronics, molecular photochemistry, and quantum chemistry Device fabrication, characterization and simulation techniques Physical and chemical processes in OLEDs including charge injection and transport, exciton generation and decay, reversible dipole reorientation, and chemical reactions Physical and chemical properties of organic semiconductors in solutions and thin-films including photoluminescence quantum yield, excited-state lifetime, and redox potential Single-molecule and condensed-matter simulations including vertical transition, nonradiative decay, spin-orbital and spin-phonon coupling, bond dissociation and charge transfer Organic Electroluminescence delivers advanced information for professionals seeking a thorough reference on the subject and for students learning about OLEDs.

From Molecular Structure to Device Performance

Organic Electroluminescence

Ferroelectric field-effect approach has been adopted by synthesizing Pb(ZrxTi1-x)O 3 (PZT)/SNNO and PZT/SIO heterostructures. Working with a prototype ferroelectric field-effect transistor, we have demonstrated robust resistance switching up to 75% and nonvolatile modulation of T MI for PZT/SNNO grown on LaAlO3 substrate. However, the PZT hardly has any effect on the SNNO for the case of STO. In both systems, we also observed a pronounced relaxation of off state resistance, showing a thermally activated behavior. The time dynamics and thermal response of the retention behavior suggest that strain-induced oxygen vacancies play a critical role in the ferroelectric field-effect instability. Meanwhile, we have also demonstrated a resistance modulation of 25% at 300 K in PZT/SNNO heterostructures. In addition, using the polarization field of PZT, we have demonstrated tunable spin relaxation. This suggests that the ferroelectric field-effect approach is a promising route to realize spintronics devices, such as the spin field-effect transistor.

This book shares with English readers Chinese theoretical and practical explorations of moral education curriculum for primary schools within the basic education curriculum reform project since 2001.The book expounds this moral education curriculum reform and focuses on three main ideas: The curriculum’s aim is to enrich children’s experiences and reflect their own lives; the curriculum’s content is originated from children’s lives; the curriculum’s structure is developed from children’s learning approach in their morality and social study. In this book, light is also shed on how to construct moral education textbooks, direct moral instruction, and moral teacher identity in the perspective of moral learning; how to knit law education and Chinese traditional culture education in moral curriculum. This is the first comprehensive book focusing on Chinese moral education curriculum reform. It will appeal to researchers, research students, and writers of moral education textbooks. It is also suitable for teacher training programs to help future teachers learn about moral education curriculum and help them effectively design and organize it for children’s morality study.

This book constitutes refereed proceedings of the Second International Workshop on Deep Learning for Human Activity Recognition, DL-HAR 2020, held in conjunction with IJCAI-PRICAI 2020, in Kyoto, Japan, in January 2021. Due to the COVID-19 pandemic the workshop was postponed to the year 2021 and held in a virtual format. The 10 presented papers were thorougly reviewed and included in the volume. They present recent research on applications of human activity recognition for various areas such as healthcare services, smart home applications, and more.
