Chapter 9 Metal-Semiconductor Contacts
inst.eecs.berkeley.eduSemiconductor Devices for Integrated Circuits (C. Hu) Slide 9-6 Schottky barrier heights of metal silicide on Si Silicide-Si interfaces are more stable than metal-silicon interfaces. After metal is deposited on Si, an annealing step is applied to form a silicide-Si contact. The term metal-silicon contact includes silicide-Si contacts.
Electronic and ionic conductivity in metal oxides
collaborations.fz-juelich.deMetal Semiconductor: intrinsic extrinsic Insulator T Semiconductors: electrons are excited over the band gap and occupy energy levels in conductivity band. Holes are created in valence band. The process is thermally activated-conductivity increase with temperature. A material with an energy gap >2.5eVis an insulator.
