Question

what is Band Theory​

Answer 1

Answer:

Band theory is a quantum model in solid state physics which gives the possible energies for electrons in a solid and gives an understanding of electrical conductivity.

Answer 2

Answer:

This is your answer friend

Explanation:

Band theory derives these bands and band gaps by examining the allowed quantum mechanical wave functions for an electron in a large, periodic lattice of atoms or molecules. Band theory has been successfully used to explain many physical properties of solids, such as electrical resistivity and optical absorption, and forms the foundation of the understanding of all solid-state devices (transistors, solar cells, etc.).
