1. The "Encyclopedia" Weight This is a massive book (often over 1300 pages). It can be intimidating for beginners. It covers so much material that it can feel encyclopedic rather than instructional. It is sometimes criticized for presenting too many variations of a topic, which can confuse a student who just wants the core concept.
2. Depth of Semiconductor Physics While it covers the physics of semiconductors, it is an applications book, not a physics book. If you are a Material Science major or a Physics major looking for deep quantum mechanics explanations of electron movement, you may find the physics sections slightly superficial compared to texts like Neaman or Pierret.
3. The Price It is an expensive textbook. This is why the search for a PDF is so common among students. --- Microelectronic Circuits Sedra Smith 8th Edition Pdf
