| Outline of Final Research Achievements |
We have fabricated dispersions of methyl- and ethyl-intercalated germanane (GeCH3 and GeEt) by liquid exfoliation approach in chlorobenzene, with sufficient concentration for thin film fabrication. Monolayers and few layers of GeCH3 and GeEt with lateral dimension of few micrometers were deposited from its dispersion onto a solid substrate, and characterized with scanning electron microscope (SEM). Physical properties and structures of the dispersions were investigated by UV-visible, FT-IR, and Raman spectroscopies. The sonication power for the dispersion process affected the interlayer distance between germanium sheets, as well as photoluminescence of layered germanane dispersions. Electroluminescence (EL) was observed in the near-infrared region from a device with a cast film from the chlorobenzene dispersion of layered germanane.
