Direct extrapolation techniques on the energy band diagram of BiVO4 thin films

Bismuth vanadate (BiVO4) is one of the n-type semiconductors which has attracted attention as one of the promising photoanodes semiconductor for photoelectrochemical water splitting due to its small optical band gap, low cost, negative conduction band edge and good stability. In this work, BiVO4 thin films is fabricated by using electrodeposition method and the XRD spectra reveal that the sample crystallizes in monoclinic scheelite type. The...
