Preface
This book surveys all aspects of the Josephson effect—from the underly-
underlying physical theory to actual and proposed engineering applications. Both ends
of this spectrum are interesting. The physical theory is novel and important for
many macroscopic quantum effects, which have a rich and yet untapped
potential for technical development. We attempt here to present more than a
survey and less than an exhaustive exposition of this wide field. Rather than to
cover everything, we have tried to uncover those aspects of theory, fabrication
technology, and device application that will be of lasting value.
Chapter 1 briefly surveys Josephson junction phenomenology. Although
the reader is assumed to have a basic knowledge of superconductivity, we
begin with the simplest possible description of Josephson structures and their
dynamic behavior. Chapter 2 presents microscopic theory in simple terms. We
discuss salient features of the underlying theory that are most useful in
appreciating experimental results. To some extent the chapters are self-
contained; for example, the reader could skip the microscopic theory (at least
on a first reading) without seriously impairing continuity. In Chapter 3 we
discuss the dependence of critical current on temperature and on junction
parameters. The static (i.e., zero voltage) behavior of "small" and "large"
junctions is considered in Chapters 4 and 5. Chapter 6 presents several
important results on the current voltage behavior of small weak links, and a
variety of weak link structures is described in Chapter 7.
What we discuss in Chapter 8 are those basic technological considerations
and certain advanced techniques that have been found useful in several
laboratories throughout the world over the past decade. We expect such
techniques to continue to be of value, especially for those who are beginning to
experiment with Josephson junctions.
Chapters 9 and 10 discuss self-resonant modes in small junctions and the
dynamical behavior of extended junctions from the perspective of modern
"soliton" theory.
The last three chapters are directed toward applications of Josephson
junctions. Chapter 11 discusses the various features of junction interactions
with periodic signals and considers such applications as mixing, parametric
amplification, and the voltage standard. Chapters 12 and 13 deal with quan-
quantum interference loops and their application to measurement of very small
magnetic fields. Finally, in Chapter 14, we describe the potential of the
Josephson junction as the basic logic and memory element in a very large
digital computer system.
