The band theory of solids is a fundamental concept in solid-state physics that explains the conduction of electricity in substances based on the arrangement of energy levels in the valence and conduction bands. Conductors have a partially filled valence band and an overlapping conduction band, allowing electrons to move freely between the two bands. This unobstructed electron flow results in the material's ability to conduct electricity. Semiconductors have a small energy gap between the valence and conduction bands, allowing some electrons to jump from the valence band to the conduction band at room temperature. The conductivity of a semiconductor increases with temperature as more electrons gain the necessary energy to transition into the conduction band. Insulators have a significant energy gap between the valence and conduction bands, preventing electrons from moving up to the conduction band. The distinction between insulators and semiconductors lies in the introduction of a small amount of impurity during the manufacturing process, known as doping, which alters the energy bands, enabling a controlled number of electrons to move into the conduction band, resulting in semiconductors' unique electrical properties.\r\n
