ABSTRACTThe Schottky barrier heights of single crystal NiSi2 layers on Si(111) have been studied by current-voltage, capacitance-voltage and activation energy techniques. Near ideal behavior is found for Schottky barriers grown on substrates cleaned at ∼820°C in ultrahigh vacuum. The Fermi level positions at the interfaces of single crystal type A and type B NiSi2 are shown to differ by ∼0.14 eV. Transmission electron microscopy demonstrated the epitaxial perfection of these suicide layers. At a cleaning temperature of 1050° C, the near surface region of lightly doped n-type Si was converted to p-type. The presence of a p-n junction was directly revealed by spreading resistance measurements and resulted in a high apparent Schottky barrier height (≥0.75 eV) which no longer bears immediate relationship to the interface Fermi level position.

AbstractElectrical behavior at single crystal silicide-silicon interfaces was studied. Schottky barrier heights were determined for epitaxial NiSi2 and CoSi2 layers grown under ultrahigh vacuum conditions on (111), (100) and (110) surfaces of Si. A dependence of Schottky barrier heights on interface structure was observed. These results favor intrinsic mechanisms for Schottky barrier formation. The advantages of having homogeneous metal-semiconductor interfaces for the study of Schottky barrier mechanisms are pointed out. In particular, the present epitaxial silicide-silicon interfaces represent ideal candidates for detailed theoretical investigations based on experimentally obtained atomic structures.
