From lighting-ferroelectric to photovoltaic properties of Pb（Zr,Ti）O3 （PZT） thin film with symmetric/asymmetric interface energy barrier

摘要

Recently,ferroelectric(FE)materials have been intensively investigated for photovoltaic(PV)applications due to the existence of internal polarization field which acts as a drive force to separate electron-hole pair.Lead zirconate titanate,Pb(Zr,Ti)O3(PZT),as one of the most commonly used ferroelectric materials,has been extensively studied
