If you've ever wanted to understand just how semiconductors, transistors, and microelectronics work--and what the future holds in store--Richard Turton's The Quantum Dot explains it in a thorough yet accessible fashion that doesn't require a degree in physics or electrical engineering to understand. Turton describes the basic principles upon which today's microelectronics are built to set the stage for a discussion of potential computing devices of the future, including quantum transistors, superconducting elements, and optoelectronics that switch with light rather than electricity. Turton is careful to provide an overview as he begins each chapter and to recap the discussion at the end, so that even if you were baffled by some of the finer details you can still pick up the gist of the section.
Product Description
Since first developed in the early sixties, silicon chip technology has made vast leaps forward. From a rudimentary circuit with a mere handful of transistors, the chip has evolved into a technological miracle, packing millions of bits of information on a surface no larger than a human thumbnail. And most experts predict that in the near future, we will see chips with over a billion bits. At the same time, this revolution in microelectronics has sparked a dramatic change in the way we live. An integral part of the computer industry, the microchip is found in everything from lasers, fax machines, and satellites to greeting cards and children's toys. And yet few people have any idea how chips work, or how so much information can be captured in such a miniscule space.
Now, in The Quantum Dot, physicist Richard Turton provides a clear, informative look at the science that lies behind the modern revolution in microelectronics and offers an intriguing glimpse of the possible future of this rapidly evolving field. Turton illuminates the development of the microchip, in a discussion that ranges from a primer on atoms and electrons, to the properties of semiconductors (most notably, silicon), to the structure of the transistor. We learn how researchers have managed to pack the tiny silicon chip with more and more bits, and we get a state-of-the-art look at the microelectronic industry today, from the newest chip materials (such as gallium arsenide, a much faster material than silicon, used in the recently released Cray 3 supercomputer) to the exotic world of high-temperature superconductors. Perhaps most interesting, Turton offers a provocative glimpse of the future of microelectronics. Here readers enter the strange realm where quantum theory prevails and where physical events contradict our intuitive perceptions. Turton shows how researchers are leaving the transistor far behind as they struggle to exploit quantum effects to create incredibly small and fast devices, such as "designer atoms" and the quantum dot. He concludes that the range of future possibilities are immense, including devices in which electrons behave not as particles but as waves, and computers in which there are no electrical signals, only beams of light.
Here then is an amazing scientific--and economic--success story, told with clarity and expertise. It will fascinate anyone curious about where modern technology is headed and what the world might look like when it gets there.

The future of microelectronics October 6, 2000
Duwayne Anderson (Saint Helens, Oregon)
18 out of 19 found this review helpful
This book consists of two parts (its not formally laid out that way, it just naturally organizes into two parts). The first part is a qualitative introduction to integrated semiconductor electronics (with emphasis on transistor junctions). The second part focuses on solid state quantum physics with emphasis on optical as well as electrical properties. There is also a smattering of material on super conducting materials and some basic material about how a digital computer works. The author's intended audience is the high school student or first-year college student who wants to pursue a degree in the sciences. An alternate audience is the informed layman who wants to be up to date at a qualitative level with recent advances in electronics and future directions in research and development. I believe the book is well written for the intended audience. Turner has an easy-to-read style, and he manages to explain things (generally) in a technically accurate way without the use of mathematics. Without the mathematical details this book is not what you'd expect in a design reference - and that's not what it's intended for. But it is an excellent book to read in advance of a rigorous quantitative class on the subject. I think it's much easier to understand physical phenomena in mathematical detail if one first obtains a qualitative "feel" for what's going on. Turner opens his book with two short chapters on matter and the origin of conductivity. He spends the next few chapters describing p-n junctions, how they are used to make transistors, and issues that limit their size and speed. Along the way he shows how transistors are used in computers both in the fabrication of basic logic elements, and also in the venerable "flip-flop" memory cell. His descriptions are clear and concise, making liberal use of figures and diagrams so that the concepts can be grasped with no particular pre-existing skills in physics or electronics. The explanation of present semiconductor physics sets the stage for later discussions about the motivation for semiconductor devices at the quantum level. He does a good job of illustrating the fact that quantum-dominated semiconductor devices will not simply be miniaturized versions of the devices populating current integrated circuits. The physics would not allow it. Rather, they will be unique devices that are designed and custom tailored using quantum theory from the ground up. The result will be new devices that have similar - though often dramatically different - operating characteristics, and that are orders of magnitude smaller than present devices, as well as faster. In illustrating the classical and quantum semiconductor circuits, Turner does a nice job of laying out the basic ideas behind these devices. In qualitative prose, he explains the exclusion principle, how it applies to fermions, and how the exclusion principle in conjunction with quantized energy states results in many of the phenomena that we observe in semiconductor devices. Turner's description of the optical properties of semiconductors flows naturally from earlier discussions. He describes the basic ideas behind a laser, though in this regard I found the descriptions somewhat lacking. Other interesting groundwork is provided in his descriptions of tunneling and Compton pairs (which are involved in super conducting). A nice feature is the glossary of terms, along with a nice list of further reading material and a good index. The book is also well illustrated throughout, with figures that add considerably to one's level of understanding. I'd recommend this book to anyone interested in a qualitative introduction to solid-state physics, electronics, or semiconductor optics. I found it enjoyable to read and rich in the sort of qualitative imagery and description that makes learning so much more enjoyable.
Great conceptual review October 21, 2004

This book is a great refresher of concepts that are driving many of our modern semiconductor devices. It does not get into heavy equations or overly complicated scenarios.
Solid State Physics Explained for the Layman November 30, 1998
3 out of 5 found this review helpful
This book gives sound, complete and comprehensible explanations for a number of solid state devices (pn diodes, FET and bipolar transistors, laser diodes, superconductors, Josephson junctions, etc). This book contains the best (most comprehensible) explanation I have ever read on the theoretical operation of bipolar transistors.
 Great book of future technology for the Lay person! April 5, 1997
4 out of 5 found this review helpful
Turton has done a wonderful job descibing the technicalities of today's computer/electronic technology. His descriptions allow the lay-person to understand the current technology and to understand where the future is taking us - probably to the Quantum Dot - and other devices. I highly reccomend it for anyone interested in the nanotechnology field as a primer
