Current-Voltage Characterization on Au-DNA-Au Junctions under the Influence of Magnetic Field

We utilized Deoxyribonucleic acid (DNA) strands immobilized between a metal gap and its behavior was investigated. The DNA strands were initially prepared using the PCR method while gaps of 10.00 μm lengths were created on gold layer deposited onto silicon substrate. Once immobilized, current-volta...

Current-Voltage Characterization on Au-DNA-Au Junctions under the Influence of Magnetic Field
description We utilized Deoxyribonucleic acid (DNA) strands immobilized between a metal gap and its behavior was investigated.

Experimental results clearly highlight the behavior of the DNA strands similar to semiconductor materials. An exponential decrease observed in the current in presence of external magnetic field suggests possible future application as a magnetic sensor.
