Current leading-edge CMOS transistors are about as small as they will get. We now have a simple, clear, very physical understanding of how these devices function, but it has not yet entered our textbooks. Besides, CMOS logic transistors, power transistors are increasingly important as are III-V heterostructure transistors for high-frequency communication. Transistor reliability is also important but rarely treated in introductory textbooks.As we begin a new era, in which making tra...

This book is the fourth volume in the New Era Electronics lecture notes series, a compilation of volumes defining the important concepts tied to the electronics transition happening in the 21st century.The lectures in this volume are about the underlying physics that makes semiconductor devices possible. The treatment is physical and intuitive — the text is descriptive, not heavily mathematical. The lectures are designed to be broadly accessible to students in science or engineerin...
