Crystal Lattices (Electrical Properties of Materials #10)
What is so special about silicon? Why are some materials more conductive to electricity than others? Where does static electricity come from? This 14-video lecture series introduces electronics from a materials perspective, and is based on a course which all freshman engineering students take at the National University of Singapore.
In this video:
00:28 Relative sizes of C, Si, and Ge atoms
01:22 Why is diamond harder than silicon?
03:08 Demonstration: cleaving a 6-inch silicon wafer
06:51 Methane, ethane, propane, and butane
08:22 Is silicon-based life theoretically possible?
08:50 Comparison of organic chemistry and silicon chemistry
12:41 Surface versus interior of a silicon crystal
13:34 Crystal structure of GaAs
Nearly 70 additional practice problems are available in the MOOC version of this course, along with supplemental videos:
