| Abstract |
本研究では、金属内包シリコン１６原子のケージ状ナノクラスターM＠Si16をマグネトロンスパッタリング法によって気相合成し、その蒸着によってナノクラスター薄膜を創製し、２光子光電子分光と顕微光電子分光とを組み合わせてその電子の振る舞いを観測した。主な成果として(1)有機表面上における3-5族金属原子内包M@Si16超原子の化学特性、(2)Lu@Si16とTa@Si16のヘテロ積層膜の作製と界面相互作用の解明、(3)2P-PEEMによる有機分子膜界面の電子ダイナミクスのイメージング、の成果を得た。
Metal atom encapsulating silicon caged nanoclusters, M@Si16, were synthesized in a gas phase by magnetron sputtering, and M@Si16 thin films were produced by size-selective deposition. The electronic properties were observed by combining two-photon photoemission spectroscopy and photoemission electron microscopy. Major scientific achievements are (1) Chemical properties of 3-5 group metal atom-encapsulating M@Si16 superatoms on the organic surface, (2) Fabrication of hetero-layered films consisting of Lu@Si16 and Ta@Si16 and elucidation of interfacial interactions, and (3) Imaging the electron dynamics at the organic molecular film interface.
