Semi Conductor Resistance

Temperature Dependence of semiconducting material Conductivity (Originally contributed by Professor E.D.H. Green) 1.0 acquirement Objectives later successfully completing this testing groundoratory workshop, including the assigned reading, the research laboratory bluesheets, the lab quizzes, and any required reports, the student will be satisfactory to: Describe how semiconductor conductivity varies with temperature. Draw a isthmus diagram for a semiconductor. Describe how doping a semiconductor improves conductivity. ready n-type and p-type semiconductors. Relate the bonding type to the materials electrical properties. follow the bandgap zip for a semiconductor from measured data in the integral region. Distinguish amidst intrinsic and extrinsic temperature regimes and identify the applicable temperature range from an examination of measured data. transport the mathematical relationships between carrier concentration and temperature in the intrinsic, extrinsic and ionisation regimes. post the functional relationship between mobility and temperature in the intrinsic, extrinsic and ionization regimes. 2.0 Resources Callister, Materials Science and Engineering: An Introduction, Chapter 19.6-19.12 Streetman, B., Solid-State Electronic Devices, 4th Ed., Prentice-Hall, 1995.
