Investigating the electronic properties of shrimp synthetic viral DNAs integrated within Schottky junctions

In this report, DNA-specific Schottky junctions were used for studying electronic properties of selected viral-derived DNAs. Two junction types were studied in this work; Al//DNA/ITO/Al and Cu/DNA/Cu using synthetic sequences of viral infecting shrimps commonly found in aquaculture. Two models based on thermionic emission theory were employed to calculate selected solid-state parameters. The ideality factor for example calculated using Cheung's method for all viral DNA samples showed values between 11.27 to 17.56 and 8.35 to 8.67 when using the Al/DNA/ITO/Al and Cu/DNA/Cu junctions, respectively. In general, characteristic profiles and parameters were observed for all DNA sequences studied using both junctions.
