本书讨论了量子井红外探测器(QWIP)的物理和应用。本报告的目的是为学生提供学习文本，并为科学家/工程师提供参考。我们假设读者具有量子力学、固态物理和半导体器件的基本背景。为了使这本书尽可能广泛地被访问，我们试图以简单和直截了当的方式来处理和呈现这些材料。我们根据以下标准选择了这本书的主题：它必须被很好地建立和理解，并且它应该已经或可能在实际应用中使用。我们已经讨论了与这一领域相关的大多数方面，但同时省略了对价带量子阱等专门主题的详细讨论。我们的书分为两部分。物理学(第一部分)从红外线探测的基础开始(第一章。2)，适用于任何光子探测器(当然，熟悉光子探测器一般概念的读者可以跳过本章)。第三章涵盖了半导体量子阱和子带间跃迁的广泛理论背景，将在接下来的章节中引用(读者可以跳过这一章。3开始)。第四章是关于光导QWIP的，随着它的进一步发展，光伏QWIP(Chap.5)，被认为是本书的核心部分--与以下所有章节相关。第六章介绍了光耦合，这对实际实现是至关重要的。关于其他效果的章节(第二章7)和相关设备(第8)是为对进一步发展感兴趣的科学家编写的，读者可以选择跳过(不影响本书的其余部分)。9)、QWIP的主要应用领域。在对QWIP热成像的一些一般性考虑之后，我们展示了QWIP阵列的典型制作步骤，一些QWIP热成像仪的性能数据，以及它们在医学、环境科学和质量控制等领域的实际应用。最后，伙计。10涵盖第二个应用领域，即超快和外差检测。这一领域大多仍处于积极研究阶段，但有可能
This book discusses the physics and applications of quantum well infrared photodetectors (QWIPs). The presentation is intended for both students as a learning text and scientists/engineers as a reference. We have assumed that the reader has a basic background of quantum mechanics, solid-state physics, and semiconductor devices. To make this book as widely accessible as possible, we have attempted to treat and present the materials in a simple and straightforward fashion. We chose the topics for the book by the following criteria: it must be well established and understood, and it should have been or potentially will be used in practical applications. We have addressed most aspects relevant for the field but have omitted at the same time detailed discussions of specialized topics such as the valence band quantum wells. Our book is organized in two parts. Physics (Part I) begins with the basics of infrared detection (Chap. 2), valid for any photon detector (of course, the reader who is familiar with the general concepts of photon detectors may skip this chapter). Chapter 3 covers a broad theoretical background on semiconductor quantum wells and intersubband transitions, which will be referenced in the following chapters (the reader may skip Chap. 3 at the beginning). Chapter 4 on photoconductive QWIPs, continued by its further development, the photovoltaic QWIP (Chap. 5), is considered as the central part of the book–relevant for all the following chapters. Chapter6 is devoted to optical coupling, which is crucial for practical implementation. The chapters on miscellaneous effects (Chap. 7) and related devices (Chap. 8) are intended for scientists interested in further developments, which the reader may choose to skip (without affecting the rest of the book).“Applications”(Part II) starts with thermal imaging (Chap. 9), the main application field of QWIPs. After some general considerations on thermal imaging using QWIPs, we showcase typical fabrication steps of QWIP arrays, performance data of some QWIP thermal imagers, and their practical use in fields like medicine, environmental sciences, and quality control. Finally, Chap. 10 covers the second application field, ie, ultrafast and heterodyne detection. This field is still mostly in the stage of active research, but might
