Essential Quantum Mechanics for Electrical Engineers

Quantum mechanics is not remote from electrical engineering: it helps explain how light sources, electronic devices, and information technologies work. Peter Deák builds that connection step by step, introducing core quantum ideas through the practical phenomena that made them matter to engineers.

Designed primarily for undergraduate electrical engineering students, this textbook balances formal foundations with applications. Its progression—from photons and electron waves to quantum states, tunneling, and many-electron systems—makes the theory easier to connect with real technologies.

Quantum ideas, seen through technology

The opening chapters trace where classical physics falls short, using lighting technology as a way into the subject. Blackbody radiation, the photoelectric effect, lasers, and electron behavior provide concrete settings for exploring energy quantization and wave-particle duality.

From there, the book develops the mathematical language of quantum mechanics: measurement, operators, observables, and quantum states. These concepts underpin later discussions of quantum wells and LEDs, electron tunneling in devices, atomic structure, and the foundations of quantum information processing.

From principles to electronic applications

Applications help keep the theory connected to engineering questions. The topics include solar cells, detectors, flash memories, tunneling devices, and quantum information hardware. Seeing the same principles recur across different technologies gives readers a useful framework for understanding why quantum mechanics matters in modern electronics.

Structured for study

Learning objectives, concise chapter summaries, self-check questions, exercises, and solutions provide a clear rhythm for working through the material. Appendices collect key classical-physics and mathematical formulas, supporting readers as they move into the quantum-mechanical treatment.

Who may find it useful?

This book is aimed chiefly at undergraduate students in electrical engineering and informatics who need an engineering-oriented introduction to quantum mechanics. It may also interest readers seeking a structured account of how quantum principles relate to semiconductors, optoelectronics, and information technology.
