Student will be able to:
1. Name two elemental semiconductor materials and some compound materials that have semiconductor properties.
2. Describe a completed transistor (IC) and relate the doping processes to the completed device; explain how it works.
3. Contrast and compare some properties of elemental semiconductors and compound semiconducting materials. Address applications.
4. Discuss doping as a method to control the resistivity of semiconductor materials.
5. Use definitions of N and P type doping to compare and contrast majority carriers and dopant materials.
6. Explain what is meant by "hole conduction" and "electron conduction".
7. Explain the axes and scales used on resistivity curves and explain what the curves are used for.
8. Discuss the speed at which carriers move in response to a given amount of energy.
