"Whether a given metal-semiconductor junction is an ohmic contact or a Schottky barrier depends on the Schottky barrier height, ΦB, of the junction. For a sufficiently large Schottky barrier height, where ΦB is significantly higher than the thermal energy kT, the semiconductor is depleted near the metal and behaves as a Schottky barrier. For lower Schottky barrier heights, the semicon… " - Is semiconductor ohmic

Witryna3. 1. 6. 2 Schottky Contact A Schottky barrier refers to a metal-semiconductor contact having a large barrier height (i.e. and low doping concentration that is less than the density of states in the conduction band or valence band. The potential barrier between the metal and the semiconductor can be identified on an energy band diagram. rick warren sbc conventionBoth ohmic contacts and Schottky barriers are dependent on the Schottky barrier height, which sets the threshold for the excess energy an electron requires to pass from the semiconductor to the metal. For the junction to admit electrons easily in both directions (ohmic contact), the barrier height must be small in at least some parts of the junction surface. To form an excellent ohmic contact (low resistance), the barrier height should be small everywhere and furthermore the inte… rick warren sermon on mary and marthaWitrynaAn electrical analysis of a metal-interlayer-semiconductor structure on high-quality Si 1-x Ge x films for non-alloyed ohmic contact. / Kim, Seung Geun; Kim, Gwang Sik; Kim, Seung Hwan et al.
