Excited State Lifetime Measurements


Book Description

Excited State Lifetime Measurements attempts to assist in clarifying and unifying the many characteristics and definitions of excited state lifetime measurements. The contents of this book are derived from a series of lectures presented to a research group in the University of New Mexico in 1967. The relevance as well as the methods and measurements of data treatment of excited state lifetimes are featured in this book. The first three chapters provide a brief discussion on concepts and applications of excited state lifetime measurements. Experimental methods and systems are also introduced in these chapters. Chapter 4 delves into more complex systems (serial decay kinetics and resonance energy transfer) while Chapter 5 focuses on the method of least squares fitting, its uses, and misuses. Chapters 6 to 8 mainly discuss the convolution integral and its different applications while Chapter 9 gives a more detailed presentation of instrumentation. The last two chapters discuss special errors and approaches to new methodologies regarding the study of the excited state lifetime measurements. The book will be useful to students and scientists including analytical chemists, photochemists, photobiologists, spectroscopists, and physicists.













Measurement of Carrier Lifetime in Semiconductors


Book Description

About 300 papers concerned with the measurement and interpretation of carrier lifetime in semiconductors are listed together with key words and a brief comment for each. Eight types of entries are included: Description of Methods, Analysis of Results, Standard Methods, Experimental Results, Theroetical Models, Auxiliary Procedures and Data, Reviews, and Books. Emphasis is placed on methods of carrying out measurements of carrier lifetime. Hence complete coverage was attempted and nearly two thirds of the entries appear in the first three categories. A large fraction of the papers listed describe the photoconductivity or photoconductive decay methods. The other most popular methods are based on diode characteristics or the photomagnetoelectric effect. In all, 35 methods for measuring carrier lifetime are represented by entries. In addition, representative papers which describe various models for recombination are included together with a number of papers which discuss the influence of surface recombination and trapping phenomena. Auxiliary procedures such as surface preparation, formation of ohmic contacts, control of temperature, and the like are described in some of the entries. Two indexes, a Key Word Index and an Author Index, are provided together with a classification of the various methods for measuring carrier lifetime. (Author).







Lifetime Spectroscopy


Book Description

Lifetime spectroscopy is one of the most sensitive diagnostic tools for the identification and analysis of impurities in semiconductors. Since it is based on the recombination process, it provides insight into precisely those defects that are relevant to semiconductor devices such as solar cells. This book introduces a transparent modeling procedure that allows a detailed theoretical evaluation of the spectroscopic potential of the different lifetime spectroscopic techniques. The various theoretical predictions are verified experimentally with the context of a comprehensive study on different metal impurities. The quality and consistency of the spectroscopic results, as explained here, confirms the excellent performance of lifetime spectroscopy.




How Will You Measure Your Life? (Harvard Business Review Classics)


Book Description

In the spring of 2010, Harvard Business School’s graduating class asked HBS professor Clay Christensen to address them—but not on how to apply his principles and thinking to their post-HBS careers. The students wanted to know how to apply his wisdom to their personal lives. He shared with them a set of guidelines that have helped him find meaning in his own life, which led to this now-classic article. Although Christensen’s thinking is rooted in his deep religious faith, these are strategies anyone can use. Since 1922, Harvard Business Review has been a leading source of breakthrough ideas in management practice. The Harvard Business Review Classics series now offers you the opportunity to make these seminal pieces a part of your permanent management library. Each highly readable volume contains a groundbreaking idea that continues to shape best practices and inspire countless managers around the world.
