All RF Cafe quizzes would make perfect fodder for employment interviews for technicians or engineers
- particularly those who are fresh out of school or are relatively new to the work world. Come to
think of it, they would make equally excellent study material for the same persons who are going to
be interviewed for a job.
Some of these books used in quizzes are available as prizes
in the monthly RF Cafe Giveaway.
Note: Many answers contain passages quoted from the text.
quiz is based on the information presented in the book, "Quantum Mechanics for Nanostructures," by Vladimir V.
Mitin, Dmitry I. Sementsov, Nizami Z. Vagidov.
