EE 331

Introduction to Materials for Electrical Engineering

Spring 2001

Prerequisites:

Chemistry 125, Math 415, Physics 133; a minimum cumulative grade point average of 2.00; and acceptance as an engineering major or written permission of the Electrical Engineering department.

Course Objectives:

In almost every case, the work of engineers finds application through materials. For example, developments in the understanding of the structure of materials and the engineering of their properties directly led to solid state devices and the resulting revolutionary growth in all aspects of electrical engineering. The primary purpose of this course is to provide an introduction to the interrelation of the structure, properties and processing of materials, with emphasis on the first two. While the course covers a broad range of materials and properties, special treatment is given to those of particular interest for electrical engineers.

 

1) Students learn about the fundamentals of structural materials.

 

2) Students learn the fundamentals of quantum mechanics.

 

3) Students apply these results to the understanding of the electronic properties of semiconductors.

Homework Policy: Homework will be due once a week. Solutions will be discussed in the lecture (time permitting) after the homework is collected. Late homework will be accepted up to two weeks after the class in which it is due or up to the last day of classes whichever is earlier. Homework will count 20% of your final grade. Penalty will be 33% for each week late. Penalty for one week late takes effect immediately following class in which it is due. After two weeks NO credit will be given.

Examinations: There will be two one-hour exams and a final exam. They will count 20%, 20% and 30% of your final grade, respectively. For each hourly exam you are permitted one "cheat sheet" comprised of an 8 ´ 11 sheet of paper which must be handwritten. For the final exam, you are permitted two "cheat sheets."

Honor System: This course is conducted in accordance with the Department of Electrical Engineering Honor System. The EE Honors System applies to students enrolled in EE courses. Copies of the EE Honor System are available in the EE Main Office, 205 Dreese.
