| 摘 要： | 通过电化学沉积方法成功生长了Co掺杂ZnO的薄膜,但并没有实现室温下的铁磁性.通过NH3等离子体的后处理,导致有一部分N原子进入了ZnO晶格替代了一部分O格位,从而在ZnO中产生空穴.在空穴间接交换作用下,ZnCoO薄膜中产生了被束缚的磁极子,产生了室温下的铁磁性.

| Abstract: | The Co-doped ZnO film was grown by electrodeposition method,the carrier concentration is 1017 cm-3,but the sample is paramagnetism.The electrons can not induce the room temperature ferromagnetism,only the introducing of additional carriers can enhance the ferromagnetic exchange action and induce the room temperature ferromagnetism.Nitrogen-doped ZnCoO film was obtained in plasma-enhanced chemical vapor deposition system,where NH3 plasma provided N source.After an ammine plasma treatment the room tempe-ratur... |
