Abstract
This paper presents the conduction mechanisms and the observation of bipolar resistive switching in nano silver incorporated gelatin (AgG) composite films. Different concentrations of commercially purchased silver nanoparticles (0.3 w/v%, 0.5 w/v%, 0.7 w/v%) were incorporated in gelatin and AgG films were spin-coated on ITO substrates. We did systematic study of I- V characteristics in these films. The film with 0.5 w/v% exhibits an abrupt increase in current at 6 V with ON/OFF ratio of more than 3 orders of magnitude. Further, the I- V characteristics revealed O-type hysteresis behaviour along with hopping type of conduction for higher nano particle concentrations of 0.5 and 0.7w/v%. However, for much dilute concentration of Ag (0.3 w/v%), the conduction is of ohmic type
