Description
The dimensions of modern semiconductor devices are reduced to the point where classical semiconductor theory, including the concepts of continuous particle concentration and continuous current, becomes questionable. Further questions relate to two-dimensional transport in the most important field-effect devices and one-dimensional transport in nanowires and carbon nanotubes.
Designed for upper-level undergraduate and graduate courses, Principles of Semiconductor Devices, Second Edition, presents the semiconductor-physics and device principles in a way that upgrades classical semiconductor theory and enables proper interpretations of numerous quantum effects in modern devices. The semiconductor theory is directly linked to practical applications, including the links to the SPICE models and parameters that are commonly used during circuit design.
The text is divided into three parts: Part I explains semiconductor physics; Part II presents the principles of operation and modeling of the fundamental junctions and transistors; and Part III provides supplementary topics, including a dedicated chapter on the physics of nanoscale devices, description of the SPICE models and equivalent circuits that are needed for circuit design, introductions to the most important specific devices (photonic devices, JFETs and MESFETs, negative-resistance diodes, and power devices), and an overview of integrated-circuit technologies. The chapters and the sections in each chapter are organized so as to enable instructors to select more rigorous and design-related topics as they see fit.
New to this Edition
* A new chapter on the physics of nanoscale devices
* A revised chapter on the energy-band model and fully reworked and updated material on crystals to include graphene and carbon nanotubes
* A revised P-N junction chapter to emphasize the current mechanisms that are relevant to modern devices
* JFETs and MESFETs in a stand-alone chapter
* Fifty-seven new problems and eleven new examples

"This book is better than other texts available on this topic because of its straightforward intuitive descriptions combined with the artfully presented, detailed, and quantitatively rendered illustrations."-- Matthew Grayson, Northeastern University"The author is eloquent and presents complex material in a logical sequence, which provides for comparatively easy reading. I find the many numerical examples (including the MatLab scripts) particularly useful from a pedagogical perspective since they invite students to become more actively engaged with the novel material and concepts. In addition, they provide visual support for some otherwise abstract mathematical relationships."--Godi Fischer, University of
Rhode Island
