[ W ] Tv Summary
- AAddqea i tF~GlM[ jAB When he joined the metal and the semiconductor, semiconductor parts, the electron affinity of the semiconductor work function metal (Fermi energy) the difference may come as a barrier. VbgL[B This is called the Schottky barrier.
- AAs^AZxB The size of the barrier depends on the type of metal, and impurity-type semiconductor, depending on different levels. gKAIVbgL[APi I[~bN jB Otherwise, proper combination of materials, Schottky barriersREZU desired conduction state only (Mick joint owner) may be.
- VbgL[AdA]A_MtdB If you are the Schottky barrier appears, the potential of the semiconductor parts, and gradually decrease away from the junction and follow the metal, equal the potential of thermal equilibrium at a point. _RwAAddB And the depletion layer between the junction point of the metal, also, and by the voltage potential difference.
