Document Summary
Students must count the number of pages in this examination question paper before beginning to write, and report any discrepancy immediately to a proctor. This examination question paper may not be taken from the examination room. Note that the questions are not equally weighted. I suggest you attempt the questions you know best rst! 1: basic quantum mechanics (15 marks total): In particular: (a) contrast it with the classical situation. (b) sketch a wave-function for a case of tunneling. (c) what e ects the degree of tunneling present? (d) give an example of a situation when tunneling is important. 3: electrons in crystals (total marks 20): When describing the electron behaviour in materials we use an e versus k relationship (e(k)). (a) (2 marks) describe what this relationship is. 4 (electrons in crystals extra page for work. ) Band structures:(cont. ) (b) (5 marks) what does the band structure of a metal, intrinsic semiconductor, and insu- lator look like.
