WebMetal-semiconductor contacts fall into two basic categories, the ohmic and the rectifying (or Schottky) contacts. An ohmic contact has a linear and symmetric current-voltage characteristic for ... WebJul 1, 1995 · Three metallization schemes, namely Al/Si, Ti-Au and TiWN-Au contacts on B-doped polycrystalline diamond films have been compared. After annealing at 450/spl deg/C in nitrogen Al/Si contacts show the lowest contact resistivity in the order of /spl sim/10/sup -7/ /spl Omega/ cm/sup 2/. TiWN-Au contacts were found to be the most stable contact …

WebNov 26, 2014 · If contact between different types of materials there can be a rectifying junction (like a galena cats-whisker crystal diode). A diode does not allow current to flow the same in both directions. Ohmic contact means taking care to avoid accidentally creating an unwanted diode where two different material conductors meet. – MarkU Nov 26, 2014 at … WebThis paper reviews ohmic and rectifying metal contacts on n- and p-type ~- and fl-SiC reported throughout that time period.
