| Abstract: | PbZr0.96Ti0.03Nb0.01O3/La0.05Sr0.05CoO3(PZNT/LSCO) heterojunction was prepared on SiO2/Si(100) by sol-gel method.The surface morphology,orientation structure,dielectric properties and energy storage properties were researched.LSCO has great strange surface,and PZNT/LSCO heterojunction show random orientation.In this paper,temperature dependence of dielectric constant and loss of PZNT/LSCO heterojunction was achieved.Energy storage density of PZNT show tendency of first up and then down,with the increase of ... |
