“The present book is intended for advanced undergraduate and graduate students in electrical engineering, physics, and material science. It also provides the necessary theoretical back-ground for researchers in optoelectronics or semiconductor devices.”  (Zentralblatt MATH, 2012)"Ahn (quantum electronics, U. of Seoul) and Park (electronic engineering, Catholic U. of Daegu, Korea) present a textbook for graduate and advanced undergraduate students in electrical engineering, physics, and materials science and engineering on quantum mechanics as it is increasingly being used in these fields. It also provides the necessary theoretical background for researchers in optoelectronics or semiconductor devices." (Book News, 1 October 2011)
