Abstract

Schottky barrier diodes (SBDs) have been fabricated with pure and zinc (Zn) doped organic interfacial layer of polyvinyl alcohol (PVA) to form Au/PVA/n-GaAs and Au/PVA(Zn-doped)/n-GaAs structures. The electrical characterization of these SBDs have also been made using their current–voltage (IV) characteristics data on both forward and reverse biases at room temperature. The main electrical parameters, such as ideality factor (n), barrier height (ΦBo), series resistance (Rs) and the voltage dependence resistance (Ri) have also been extracted from the IV data to compare the Zn-doped and undoped polymer interfacial layer SBDs. The rectifying ratio values of Au/PVA/n-GaAs and Au/PVA(Zn-doped)/n-GaAs SBDs have been obtained as 105 and 107, respectively, at (± 2 V). Consequently, the comparison of the polymer interfacial layer SBDs indicates that the Zn-doped SBDs have given better results than the undoped SBDs when considering the main electrical parameters at room temperature.
