Differential Depletion Charge Density of the Approximation of Schottky Diodes as Ohmic Annealed a Variety of Temperatures

Abstract

This study aimed to investigate the differential depletion charge density for (Ag,Cu, Ni) /n-Si/Al Schottky diodes which depend on ohmic contact temperatures.Ohmic contact temperature defines the Schottky diode parameters. Furthermore,ohmic temperature is concerned with diode quality. In general, depletion chargedensity is determined as depending on built-in potential. The differential depletioncharge density is smaller than zero-voltage depletion charge density (V = 0, Vbi ≠0) in the case of forward bias and higher than the zero-voltage depletion chargedensity for reverse bias. When the depletion charge density formula was expandedinto a series, new equations revealed appreciable results. Boundary-values werefound for differential depletion charge density using normal and expanded formulae.
