鐵電疇壁在BiFeO3反常光伏效應中的作用-nature communication-2013

Role of domain walls in the abnormal photovoltaic effect in BiFeO3 nature communication-2013 關鍵詞: 鐵酸鉍 光伏效應 鐵電疇 疇壁 abstract Recently, the anomalous photovoltaic (PV) effect in BiFeO3 (BFO) thin films, which resulted in open circuit voltages (Voc) considerably larger than the band gap of the material, has generated a revival of the entire field of photoferroelectrics. Here, via temperature-dependent PV studies, we prove that the bulk photovoltaic (BPV) effect, which has been studied in the past for many non-centrosymmetric materials, is at the origin of the anomalous PV effect in BFO films. Moreover, we show that irrespective of the measurement geometry, Voc as high as 50 V can be achieved by controlling the conductivity of domain walls (DW). We also show that photoconductivity of the DW is markedly higher than in the bulk of BFO.[ Last edited by wiseroy on 2014-1-12 at 23:00 ] |
