摘要: Orthoferrite perovskite LaFeO3 has been of great interest with its versatility for potential applications in electromagnetic, catalytic, and sensing applications. Nanowires have shown as active building blocks assembling a variety nanoscale devices, nevertheless far less is known about the characteristics nanowires. Here, we show that nanowires Ga doping can be produced by electrospinning, yielding formation specific nanostructure fine crystallite array arranged along nanowire framework. The structure chemical state analyses were performed to reveal nanostructural difference induced substitution. Furthermore, La(Fe,Ga)O3 devices built showed temperature field dependence on electric transport following Poole-Frenkel conduction model. dramatic conductance lowering was observed explained change trap energy carrier hopping.
