Description
本実施例では、まず、高真空マグネトロンスパッタ装置を用い、MgO(100)からなる基板2上に、740℃の温度で、Feを1.0nmの厚さにスパッタリングした後、Ar95体積%、O25体積%からなる酸素含有ガスを供給して、該スパッタリングにより形成されたFe層の表面を酸化した。次に、室温(65℃)でMgOからなる形態規定材料を1.0nmの厚さにスパッタリングした。そして、前記形態規定材料上にさらに、740℃の温度でFeを1.0nmの厚さにスパッタリングした後、前記酸素含有ガスを供給して、該スパッタリングにより形成されたFe層の表面を酸化した。
本比較例では、まず、高真空マグネトロンスパッタ装置を用い、Si基板上に、25℃の温度でAlを5.0nmの厚さにスパッタリングした。次に、25℃の温度でFeを1.5nmの厚さにスパッタリングし、さらに25℃の温度でAlを1.0nmの厚さにスパッタリングすることによりカーボンナノチューブ成長用基板を得た。得られたカーボンナノチューブ成長用基板の透過型電子顕微鏡写真を図5に示す。
