Lecture Notes

• Lecture 19, Mar. 15: Superconductivity (pdf of the ppt presentation)

• Lecture 18, Mar. 13: Magnetism (pdf of the ppt presentation)

• Lecture 17, Mar. 8: Quantum Oscillations

• Lecture 16, Mar. 6: Metals, Insulators, Semi-classical EOM, Hole

  • Classroom activity sheet (answers wanted, just like other ones) Wilson rule found in LN 14.

• Lecture 15, Feb. 28: Some considerations of the tight binding band (guest lecture; note-free)

• Lecture 14, Feb. 23: Nearly free electron and tight binding bands

• Lecture 13, Feb. 21: Bloch Theorem

  • Classroom activity sheet, included and fully explained in the last section.

• Lecture 12, Feb. 16: Free electrons, Transport properties

• Lecture 11, Feb. 14: Free electrons, Thermal properties

• Lectures 9,10, Feb. 7,9: Debye law, Anharmonic effects

  • Classroom activity sheets (answers wanted, just like other ones)

• Lecture 8, Feb. 2: Measuring phonons, Einstein model, DOS

• Lecture 7, Jan. 31: Acoustic phonons and optical phonons

  • Classroom activity sheets: Please note that for any class room activity sheets for which solutions are not available here, you can write your solutions and submit them. That will give you extra credit. There is no time limit for this. Even if other students have submitted solutions, you can submit yours if yours point out some nice aspect previously neglected. Even if the solution was explained in class, do not hesitate expressing the same solution in your language -- it is very important! The extra credit points will be good for recovering from some lost points in homework etc.

• Lecture 6, Jan. 26: BvK Boundary Condition, Phonons

• Lecture 5, Jan. 24: Structure Factor, Atomic Form Factor

• Lecture 4, Jan. 19: Diffraction, Bloch sum

  • Complete crystal groups

  • Crystal structure data base: use "Demo", which is often quite good enough.

  • Corrections: two words (one in page 4 and the other in page 5: see words marked in red).

• Lecture 3, Jan. 17: Cell and Reciprocal Lattice

  • Classroom activity sheets: submit your answers! (extra credit)

• Lecture 2, Jan. 12: Basis, Bravais Lattice, Miller Indices

  • Classroom activity sheets (with answers)

  • Please note step 5 of page 4 – Miller indices are integers!

  • Additions: pages 2 (black hand-writing) and 4 (red on rule 5).

• Lecture 1, Jan. 10: Atoms, Molecules

  • Page 2: more explanation added to the Bohr-Sommerfeld quantization rule. — Sam, 9:59PM, Jan 11, 2012
