Abstract

Rectifying contacts on semiconducting type IIb diamond crystals are readily established with any conducting material system including elemental metals, highly doped semiconductors, silicides and carbides. However, for a given surface preparation using oxidizing wet chemicals and in the absence of a surface reaction, barrier heights are observed to be constant regardless of the metal work function. In this report it is demonstrated that an adjustment of the barrier height can be achieved by employing a premetallization low-dose low-energy ion-implantation step.
