Requirements

Lectures: The goal of class time is to emphasize important concepts covered in the textbook, introduce topics not in the text, and highlight common conceptual and problem-solving pitfalls. It is my responsibility to present this material for your coherently and create an environment in which you will feel comfortable participating. It is your responsibility to take me up on my offer to participate and to prepare yourself for the class by reading the material and working sample problems. Attendance for all lectures and discussions is strongly recommended.

Quizzes: Short quizzes will be given in the middle or at the end of the class to test student class participation.

Resarch Track

Students opting to work on Research Track will not have to solve homework problems or conduct two mini-research projects, but they will be required to take in-class quizzes. Instead, they will spend whole semester working on an open ended project via computer simulations. If successful, students will receive grade A and could also publish their result in the form of a journal article. If unsuccessful, students will have to take oral exam at the end of the course.

Conventional Track

Homeworks: Homework will be assigned on Tuesdays and it is due by next Tuesday (can be handed in the class or emailed as PDF).

Exams: There will be no traditional exams.

Mini-Research Projects: Instead of traditional exams, two mini-research projects will be assigned dealing with modeling of transport in nanostructures of contemporary interest. The first project will be reported on in the form of a journal article (two column style with text and equations, see Example), while the second one will be presented in the form of the poster session at the end of the semester.

Academic Honesty

The policy on academic honesty as stated in the Student Guide to University Policies will be followed during this course. In particular, collaboration on homework assignments and in-class activities is permitted and encouraged. However, you cannot submit identical reports/posters.

Grading

• The final score will be determined as a weighted average of different class activities listed above using the following formula:
  • Homework - 30%,
  • Quiz - 10 %,
  • Midterm and final Research Project - 60%.

• Here is a guideline for your final letter grade, as a percentage of the total number of points:
  • 93 - 100 -> A
  • 90 - 92 -> A-
  • 85 - 89 -> B+
  • 80 - 84 -> B
  • 75 - 79 -> B-
  • 70 - 74 -> C+
  • 65 - 69 -> C
  • 60 - 64 -> C-
  • 57 - 59 -> D+
  • 53 - 56 -> D
  • 50 - 52 -> D-
  • < 50 -> F

These numbers may be lowered, depending upon numerous factors, but will not be raised (i.e., if you have 90 average you are assured of at least an A-). The course grades are not curved.

• Grading of overdue homework: Homeworks submitted after the deadline will incur a penalty 5 points for each 24 hour period. After eight days, the maximum possible grade is set at 60 points.
