Goal of the course
Objectives of the course: Course is planned for 1st year graduate and 4th year undergraduate students. It starts with an intensive review of Quantum Mechanics and its application to problems that can be of interest to microelectronics or optoelectronics. The emphasis is in understanding the basic properties of the physical system and description in the language of quantum mechanics.Prerequisites: The course is designed for students in Physics but also with Engineering background. While the basic Q.M. is covered , previous knowledge of Quantum Mechanics or Solid State physics and Mathematics is very useful.
