Lecture 17, Slide 3 EECS40, Fall 2003 Prof. King What is a Semiconductor? Low resistivity => “conductor” High resistivity => “insulator” Intermediate resistivity => “semiconductor” – Generally, the semiconductor material used in integrated-circuit devices is crystalline In recent years, however, non-crystalline semiconductors have become commercially very important polycrystalline amorphous crystalline Lecture 17, Slide 4 EECS40, Fall 2003 Prof. King Semiconductor Materials Elemental : Compound : Alloy :

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
