Semiconductor Heterojunctions investigates various aspects of semiconductor heterojunctions. Topics covered include the theory of heterojunctions and their energy band profiles, electrical and optoelectronic properties, and methods of preparation. A number of heterojunction devices are also considered, from photovoltaic converters to photodiodes, transistors, and injection lasers. Comprised of eight chapters, this volume begins with an overview of the theory of heterojunctions and a discussion on abrupt isotype and anisotype heterojunctions, along with graded heterojunctions. The reader is then introduced to the energy band profiles of isotype and anisotype heterojunctions, the practical aspects of their fabrication and characterization, and their electronic and optoelectronic properties. Some methods used in the preparation of heterojunctions are also described, including the chemical method, solution growth method, alloying method, and sputtering method. The remaining chapters focus on the characterization of the grown layers, examples of heterojunction devices, and experimental work on heterojunctions. This monograph is intended for research workers and graduate students.

Gandhian economics is based on a paradigm that is fundamentally different from that of modern economics. This book attempts to present a philosophical analysis of Gandhian economic thought. It explores the Gandhian world-view, its accompanying value system and concepts, and examines in detail, how they bear upon economic principles and policy with special reference to the solution of the existing problems. The book offers a penetrating analysis of the dynamics of Gandhian thought and action. The study takes a refreshingly new approach to the concept of man and society, goal of life, meaning of growth and the means to achieve the same while interpreting Gandhian economic thought. In a lucid manner it explores the economic ''ends'' and ‘means'' put forward by Mahatma Gandhi for peace and prosperity of mankind. In a revealing analysis, the book presents that the paradigm underlying modern economics is responsible for creating world economic crisis, incapable of being tackled by the traditional economic tools. The dismal failure of both marxism and liberalism to resolve the situation, calling into question the very foundations of economic is further shown. Gandhian holistic economics offering an alternative model of development needs a serious consideration in the present troubled times. Transformation in man and creation of economic structures based on a holistic paradigm is the challenge of the day. The intellectual readers will find th book to be fascinating but those who Ic challenges, wjll take it to be invaluable
