Semiconductors include the following elements; Boron, Silicon, Germanium, and Arsenic. These are also known as Metalloids, and they seem metal but are really Brittle. They can also generally form alloys with other metals. Silicon and Germanium become electrical under special circumstances. Solids under other circumstances, and they are mostly nonmetallic in their chemical behavior.
Site I got this information from: http://www.ducksters.com/science/chemistry/metalloids.php
These are compound semiconductors.
This is considered a semiconductor.
Did you know that there is a semiconductor company? This is what they make.
