AAO mask assisted high density array of epitaxial BiFeO3 nanoislands on conducting substrate : multiferroic at room temperature. |
| 초록 |
Magnetoelectric BiFeO3 (BFO) has attracted great interest due to its promising application to magnetoelectric devices. To study the ferroelectric and ferromagnetic properties of nano-sized BFO, we prepared the high density array of BFO nanoislands on a single crystalline substrate by using porous polymer template. The porous template was obtained by plasma etching on a polystyrene film with alumina membrane as an etching mask. The BFO precursor was dropped into the porous template, followed by spin-coated. PS nanoporous template was completely removed at a high temperature. During this process, the BFO nanoislands were epitaxially crystallized on the substrate. Crystal structure, ferroelectricity, and ferromagneticity of BFO nanoislands were studied by X-ray diffraction, piezoresponse force microscopy, and magnetic force microscopy, respectively. |
