Semiconductor Physics

Semiconductor physics involves materials, like silicon, that conduct electricity under certain conditions but not others. They can effectively 'control' an electrical current. When you add impurities, they can create an excess of negative or positive charges, altering their conductivity. This property makes semiconductors essential in devices like transistors used in most electronics, regulating or amplifying the electric current as needed. Semiconductor physics is the study of how these fascinating materials function and how to use them effectively.
