·       Nov. 28, 2010: Here is the review for Quiz 3.

·       Nov. 16, 2010: Here is the statistics so far. See you good (or bad) you have been doing. Come to see me if you think you are qualified for various rescue plans. Note: the plots are based on the assumption that we have a normal distribution.

·       Nov. 3, 2010: Here is the review for Quiz 2.

·       Oct. 22, 2010: Quiz #1 statistics, Average 2.44, STD 1.06, the highest score 3.9 out of 4.0. Here is why I am a nice guy. If you are one of those who received a score more than one sigma below the average (i.e., < 1.38), I have a rescue plan, so contact me if you are interested in.

·       Oct. 20, 2010: You may use a 8.5x11 piece of paper (front and back) for the midterm. Write down whatever you think is useful for the midterm. Bring a calculator if you want to.

·       Oct. 16, 2010: The midterm review slides are posted. We will review the slides on 10/19.

Important Information

Discussion sessions

The goal for the discussion sessions is to allow you to review lecture topics in more detail and discuss strategies to solve homework problems, both under the guidance of the TA.

Laboratory sessions

  • General Information
  • Laboratory Report Format
  • Laboratory Groups and times (TBA)
  • Laboratory session reports are due at the beginning of the following laboratory session. For each day a report is late 5% will be subtracted from the grade.
  • You have to pass the class in order to pass the laboratory sessions.
  • You will only be able to do the experiments while the TA is present, so showing up for the scheduled laboratory session times is mandatory. BE161 has computers that you can use for writing your reports if you wish.
  • Since you don't have 24/7 access to the lab, attendance for your session is mandatory to pass the lab.

Remember: You need to take the applet quiz by the time the report for the accompanying experiment is due.

The applets count 50% towards the grade for that laboratory session.

The following is a tentative laboratory schedule. The schedule below will be updated when the quarter begins.

Course Objectives
The fundamental electrical, optical, and magnetic properties of materials, with emphasis on semiconductors: chemical bonds, crystal structures, energy bands. Electrical and thermal conduction. Optical and magnetic properties. Students must concurrently enroll in course145L.

Course Prerequisites
EE145/L is a required course for EE undergraduates. Other Engineering or Science majors with proper prerequisites are welcome to enroll. Prerequisites (or equivalent at community college) are: Physics/5abc or 6abc, Math/differential equations.

Course Expectations
Learning occurs by the active involvement of the student. Consequently there will be many different opportunities for active learning, such as cooperative problem-solving in lab. The student is expected to come to class prepared to think and learn. The lecture period will be used to establish fundamental concepts. The lab periods will be used to practice the engineering skills of problem-solving and data acquisition and analysis.

During both lab and lecture time, you will be asked to participate in solving problems. Always bring your calculator to both lab and lecture. It also is helpful to bring your textbook along.

To get the most out of this class, you need to read the assigned sections in the textbook before coming to class, and most importantly to read the assigned Lab Notes before coming to lab sections. There will be quizzes in the lab sessions. It is advisable to review the Learning Objectives frequently to keep track of your own progress. Don't feel that you have to be failing the course to come see your instructor or TA; come to ask questions.

Working Together
You are encouraged to work in groups and discuss the homework assignments. However, each has to write his/her own solution and fully understand them.

Homework Assignments
Homework will be assigned and collected during class sessions, and will generally follow a weekly sequence. Solutions will be handed out (or posted at our web site) on the date of collection. Thus, late homework will not be accepted or graded. Homework is graded in terms of it being complete, well organized, readable and showing evidence of thoughtful attention to the problem itself. Sloppy submissions will not be considered for grading.

Grading Method
The course will not be graded on a curve. It is possible for everyone to earn an "A" or for everyone to earn an "F". Your final course grade does not depend in any way upon anyone else's performance. Thus it is to your benefit to find a group of people you can study with and to help each other learn. Passing the final is mandatory in order to pass the class. You should be aware of academic Integrity and plagiarism.
