摘要：
A self-assembly technique for high density (similar to 1 x 10(11)cm(-2)) beta-FeSi2 nanodots epitaxially grown on Si (001) substrates was developed using a codeposition method of Fe and Si on ultrathin SiO2 films with Si nuclei. Photoabsorption spectra of individual nanodots and their photoabsorption maps at the direct-transition photoabsorption edge were obtained using electric field modulation spectroscopy combined with scanning tunneling microscopy with a nanometer spatial resolution.
