PHYS 3000 Final: PHYS 3000 Final Exam 2007
Document Summary
Phys 3000 physics & physical oceanography, memorial university of newfoundland fall 2007. This exam addresses the materials physics involved in three di erent kinds of semiconductor devices. To receive full credit, you must answer the questions clearly and completely; support your answer with a quantitative relation or formula whenever possible. You have until 11:00 (approximately 120 minutes from now) to complete this test. Equations, constants, and semiconductor parameter tables for your use are at the end of this test. * if you are using your own formula sheet (one 8. 5 x 11 piece, both sides, containing only formulae no gures, diagrams, tables, or annotation), you must hand it in with your exam. Assume that you start with the silicon-oxide-silicon layers shown below (left) and end up with the suspended silicon piece shown below (right). Laser pointers are now widely available because of the development of diode lasers. (a) [4 points] many lasers are pn junction diodes.
