WebbUn contact ohmique est un contact métal- semi-conducteur avec une très faible résistance de contact. Il est dit ohmique lorsque le courant I est proportionnel à la tension V avec un facteur de proportionnalité . La résistance spécifique de contact r c est le produit de Rc par la surface de contact. Webb23 jan. 2014 · The current-voltage characteristics of Ni contacts with the surfaces of ZnO thin films as well as single crystal (0001) ZnO substrate are investigated. The ZnO thin film shows a conversion from Ohmic to rectifying behavior when annealed at 800°C. Similar findings are also found on the Zn-polar surface of (0001) ZnO. The O-polar surface, …

WebbAn ohmic contact is a region on a semiconductor device that has been prepared so that the current-voltage (I-V) curve of the device is linear and symmetric. If the I-V characteristic is non-linear and asymmetric, the contact is not ohmic, but is a blocking or Schottky contact. Typical ohmic contacts on semiconductors are sputtered or evaporated … Webb네이버 블로그
