Nettet29. sep. 2024 · Intrinsic Semiconductors. An intrinsic semiconductor is a pure material with a small band gap. For every electron that jumps into the conduction band, the missing electron will generate a hole that can move freely in the valence band. Both conduction band electrons and valence band holes can contribute to conducting electricity. Nettet23. des. 2024 · Holes move in just the same way electrons do. One minor difference is that because the curvature of the E-k curve for the valence band is different from the curvature for the conduction band, holes and electrons have different effective masses. Other than that, they move the same way. If electrons can move across the junction, holes can do …
