silicon carbide free electrons

What are the Major Reasons Behind Silicon Uses in …

The conduction or flow of charge in semiconductors is due to the movement of free electrons or holes. If you are familiar with the periodic table, you must be aware of the groups in a periodic table. Semiconductor materials are usually present in the group 4 of periodic table or also present as a coination of group 3 and group 6, or as a coination of group 2 and group 4 as well.
