Abstract :
The current-voltage (I-V) characteristics of nickel mono-silicide/n-Si Schottky diodes fabricated at different temperature and measured over a temperature range of 78 to 299 K have been interpreted on the basis of thermionic emission (TE) across an inhomogeneous Schottky contact. The experiment shows that the apparent barrier height φap-1/T plot is a straight line within the whole experimental temperature for samples annealed at temperature ranging from 500°C to 600°C, however, for other samples annealed at temperature below 500°C and above 600°C the φap-1/T Plots become more complicated. The linear case shows the Schottky barrier height inhomogeneities (SBHI) obeys single Gaussian distribution
