采用反应沉积外延(RDE)和分子束外延(MBE)两步法在Si(111)衬底上生长了100 nm厚的BaSi 2外延薄膜。在RDE期间,Ba沉积速率和持续时间分别从0.25至1.0 nm/min和从5至120 min变化。平面图透射电子显微照片表明,MBE生长的BaSi 2的晶粒尺寸显著依赖于RDE生长条件,从约0.2 μ m到4 μm以上不等。
100-nm-thick BaSi2 epitaxial films were grown on Si(111) substrates by a two-step growth method including reactive deposition epitaxy (RDE) and molecular beam epitaxy (MBE). The Ba deposition rate and duration were varied from 0.25 to 1.0 nm/min and from 5 to 120 min during RDE, respectively. Plan-view transmission electron micrographs indicated that the grain size in the MBE-grown BaSi2 was significantly dependent on the RDE growth conditions and was varied from approximately 0.2 to more than 4 µm.
