Özet:

 


 
                         This work was prepared in two sections; the first section describes how to alloy Schottky diodes and aims
to understand how metal alloys affect the essential parameters of Schottky diodes at the metal-semiconductor interface.
The second section covers the varying differential depletion length in (Cu% Ni%)/n-Si/Al binary-alloyed Schottky diodes.
After collecting data, the characteristics of Schottky diodes are calculated by plotting them with an increasing percentage
ratio of the first element. We see that alloyed Schottky diode characteristics significantly depend on the mass percentage
ratio of the first element. Significant results are seen: first, Vbi (built-in potential) directly affects the characteristics
of Schottky diodes with a turning point occurring at the Vbi point on the axis, and second, the built-in potential plays
a key role in Schottky diode characteristics. Estimation of the depletion length depends on the built-in potential. For
the forward and reverse bias cases, the depletion length versus voltage graphs are identical, but with their symmetry
mirrored. Analyzing the differential depletion lengths, it is easily seen that they have higher or lower values compared
to the zero depletion length for the forward and reverse bias cases, respectively. When the depletion length formula is
expanded in a series, new equations are obtained to show significant effects on Schottky diode characteristics.
