**Text:***Introduction to Solid State Physics* by Charles Kittel

Other good books :

Ashcroft & Mermin, *Solid State Physics* (Brooks-Cole, 1976)

Kittel, *Quantum Theory of Solids* (Wiley, 1987)

Ziman, *Principles of the Theory of Solids *(Cambridge University Press, 1979)

Yu & Cardona, *Fundamentals of Semiconductors: Physics and Material Properties* (Springer, 2010)

**Grading:**

Grades are based on homework, a course project, the midterm, and the final exam:

**Homework: 30%****Project: 10%****Midterm: 25%****Final exam: 35%**

**Homework** will be assigned *bi-weekly*, and counts for **30%** of your grade. Assignments will be posted here on the website. Homework must be turned into the 410/510 Solid State Physics box in the basement of Willamette Hall on **Thursday by 7 pm**, unless otherwise specified. The course GTFs will be available several hours per week to assist you in your homework. Here are some homework guidelines:

- Late homework will be marked down 25% for the first day; homework turned in more than one day late will be marked as a zero. If you have a legitimate reason for turning in homework late, please let me know ASAP.

- You need to complete homework on your own. Group work is encouraged, but you must write out your own solutions. Also, if you get stuck on a problem and use resources such as books, online material,
*etc.*to assist you on the problem, you are required to cite the resources you have used. Looking up answers to homework can be incredibly useful to your learning, but be sure to give the appropriate credit.

- Your homework must be neat and legible; messy, illegible homework will be returned ungraded and marked as a zero. Remember, messy work is indicative of a messy mind; slow down and do it right ☺.

- The graduate students enrolled in the course will be assigned a few extra problems on each homework set. Undergraduates that choose to complete these additional problems will receive extra credit.

You will need to choose your own unique **Course Project **that is related to the course content. Please discuss your proposed project with me before beginning; a short written proposal will be due by **Friday, May 8 ^{th}**. Ideas for projects include writing a paper on a solid-state topic, performing a numerical simulation or calculation (

*e.g.*a band structure calculation), making yourself solid state physics note cards,

*etc*. The project is

**10%**of your grade and is due by the time of the Final Exam (

**Monday June 8**)

^{th}, 10:15 am.The** Midterm** will be on **Monday, May 4^{th}, in class**. It will be closed book, closed notes (one single-sided 8.5 “ X 11 “ formula sheet allowed), and counts for

**25%**of your grade. Undergraduates and graduates will be graded separately. No excuses other than medical ones will be accepted for missing/rescheduling the exam.

The **Final exam** is scheduled for **Monday, June 8 ^{th}, 10:15 am.** It will be closed book, closed notes (two single-sided 8.5 “ X 11 “ formula sheets, or equivalent, allowed), and counts for 3

**5%**of your grade. Undergraduates and graduates will be graded separately. No excuses other than medical ones will be accepted for missing/rescheduling the exam.

**Course Documents: **(Check here for lecture notes, exams, exam solutions, and additional reading.)

**Approximate Course Schedule** (This is just a guess of what we will cover this quarter and when we will cover it. The schedule also lets you know what chapters of Kittel you need to be reading. Please note that this schedule will likely be altered.)

Grading policy

Here are guidelines for your final grade, as the percentage of the total number of points:

85-100 A

82-84 A-

65-81 B/B+

50-64 C/C+

40-49 D/D+

0-39 F

Depending on the overall performance of the class, these numbers may be lowered but not raised.

an algebraic solution to each problem MUST be accompanied by the dimensional analysis of the result.

Without such an analysis, you will get no more than 75% of the credit, even if the solution is otherwise

*correct*. On the other hand, if you do not know how to solve the problem but construct an approximate result, using the dimensional analysis, you may get up to 25% of the credit

Academic Honesty

All students are required to abide by the Academic Honesty Guidelinesaccepted by the University.

Consistent with university policy, any incident of academic dishonesty in this course will be reported to the Dean of Students Office. It is normal and reasonable for students in a Physics course to work together on homework assignments. However, following the normal practices of co-authorship accepted in academic institutions, yo must list all people who you collaborated with on a particular assignment. This Instructor defines academic dishonesty as plagiarism(including copying solutions from Internet sources), fabricating data (for example, ''fixing" a solution so that it gives the correct answer), giving or receiving any unauthorized assistance on academic work, and interfering with the academic work of other students. Supplying a false or fabricated excuse for missed academic work is also academic dishonesty. If the incident is the student's first offense at UF, the student will receive a reduced or failing grade in PHY6426. If not, the Dean of Students Office will decide the appropriate sanction.

__Students with disabilities__

Students requesting classroom accommodation must first register with the Dean of Students Office. The Dean of Students Office will provide documentation to the student who must then provide this documentation to the Instructor when requesting accommodation.
