Abstract

In this paper, the study of electrical properties of Au/methyl-red/Ag surface type Schottky diode by current-voltage (I-V) characteristics is reported. The I-V characteristics of the Schottky diode showed the very high rectifying behavior. The rectification ratio was found in order of 105. The values of ideality factor n and barrier height b φ of Au/methyl-red/Ag Schottky diode were calculated. The average values of n and b φ were found about 1.58 and 0.24 V, respectively. The effect of series resistance was also investigated. The average value of RS values was calculated about 1.1 kΩ..
