Abstract:The effect of oxygen on the electrical conductance and local structural properties of BiFeO3 (BFO) thin films on SiO2/Si substrates grown by RF magnetron sputtering was investigated. The conductivities of BFO were studied in a planar electrode with blue light irradiation. The BFO films grown with oxygen (BFO-O2) show a large conductivity increase, which is 12.66 times more than the BFO grown without oxygen (BFO), and the conductivity change is entirely caused by the BFO thin films. To explain the mechanism of … Show more
