商品描述
This book explores fundamental and experimental aspects of excitons in semiconductors. It begins with an introduction to crystal lattice, band structure of solids, effective mass theory, and holes. It then explores the binding energy of various excitons and their complexes (such as trions and biexcitons) in different dimensions within the framework of effective mass approximation, discusses the absorption and emission of photons during their creation and recombination processes providing experimental examples in photo-absorption and photoluminescence (PL) spectroscopy. Theoretical foundations for calculating the dielectric function associated with excitons along with the concept of 'exciton-polaritons' are introduced. The book also examines the interaction between excitons and phonons, which is illustrated with experimental findings. Further, it discusses the effects of magnetic field on the energy eigenstates of excitons, and talks about polarization-resolved spectroscopy under magnetic field for identifying excitons and obtaining deeper insight of the excitonic structure as well as the semiconductor band structure. Lastly, it delves into the manybody effects i.e. Bose-Einstein condensation of excitons and excitonic Mott transition, presenting recent experimental findings and potential applications.
Throughout, emphasis is placed on elucidating fundamental concepts while keeping readers abreast of the latest developments in the field. With a focus on experimental methods and data interpretation, the book serves as an invaluable resource for both graduate students and research scholars.
商品描述(中文翻譯)
這本書探討了半導體中激子（excitons）的基本和實驗性質。書中首先介紹了晶格結構、固體的能帶結構、有效質量理論以及孔（holes）。接著，書中探討了在有效質量近似框架下，各種激子及其複合體（如三激子（trions）和雙激子（biexcitons））在不同維度中的束縛能，並討論了在激子生成和重組過程中光子的吸收和發射，提供了光吸收和光致發光（PL）光譜的實驗範例。書中還介紹了計算與激子相關的介電函數的理論基礎，以及“激子極化子（exciton-polaritons）”的概念。書中還檢視了激子與聲子（phonons）之間的相互作用，並用實驗結果進行說明。此外，書中討論了磁場對激子的能量本徵態的影響，並介紹了在磁場下的偏振解析光譜技術，以識別激子並深入了解激子結構及半導體能帶結構。最後，書中深入探討了多體效應，即激子的玻色-愛因斯坦凝聚（Bose-Einstein condensation）和激子莫特轉變（exciton Mott transition），並呈現了最近的實驗發現及潛在應用。
整體而言，書中強調闡明基本概念，同時讓讀者了解該領域的最新發展。專注於實驗方法和數據解釋，這本書對於研究生和研究學者來說都是一個寶貴的資源。
作者簡介
After earning his PhD in Physics from Jawaharlal Nehru University (JNU) in New Delhi, India, in 2001, the author pursued several years of postdoctoral research at the Paul Drude Institut für Festkörperelektronik in Berlin, Germany, as a scientist. He also conducted research at the University of Duisburg-Essen, Duisburg, Germany, as an EU Guest Scientist under a Marie Curie Excellence Grant, focusing on epitaxial growth and the optical and magnetic properties of wide band-gap semiconductors. In 2006, he joined the faculty of Physics at the Indian Institute of Technology Bombay (IITB) in Mumbai, India. Presently, he holds the position of professor and department head in the Physics department at the same institute. With approximately 30 years of research experience, his expertise lies in the study of excitons in semiconducting systems of various dimensions, including epitaxial layers, heterojunctions, nanowires, nanoparticles, and 2D semiconductors. He has authored over 120 peer-reviewed research publications in prestigious international journals. Over the course of 18 years of teaching at IITB, he has instructed numerous undergraduate and postgraduate level courses in condensed matter physics, with a focus on semiconductor physics and the physics of semiconductor devices.
