Al and Zr Schottky contacts become (a) rectifying on p-type Ge and (b) Ohmic on n-type Ge, after passivation treatment.
Barrier heights for Schottky contacts with and without passivation, plotted against the ideal metal work functions. The best slope has a value of 0.95, as shown by the dotted line.
XPS measurements showing (a) the absence of observed after HCl-HBr cleaning, and after treatment with ammonium sulfide. (b) Suppression of as observed from the core level spectrum, due to bonding between Ge and S.
Parameter values obtained from passivated devices by fitting experimental data with the thermionic emission model.
