Notes:
High quality ruthenium Schottky barrier diodes were fabricated on epitaxially grown n-GaAs, by the electron beam evaporation of Ru. Annealing studies were carried out in vacuum and in air. The effective barrier height and the flatband barrier height of the as-deposited Schottky contacts were 0.86 and 0.91 eV, respectively. These barrier heights reached their respective maximum values of 0.93 and 0.96 eV, after annealing at 450 °C in vacuum. The electrical characteristics of a third set of contacts, which was subjected to prolonged (1000 min) annealing at 400 °C in vacuum, showed no measureable signs of degradation.
