The textbook Microelectronics" by Jacob Millman and Arvin Grabel (2nd Edition, 1987)
How Millman & Grabel solves it:
Comprehensive Scope: Covers a broad spectrum of topics, including diode and transistor operation, analog and digital circuit design, and modern integrated circuit (IC) fabrication.
The opening chapters provide a deep dive into the physics of solid-state materials. Unlike texts that rely heavily on black-box models early on, Millman and Grabel take the time to explain energy bands, the Fermi level, and the transport phenomena (diffusion and drift) that govern carrier movement.
