240. Strain and Intermixing in Single Ge/Si Quantum Dots Observed by Tip-enhanced Raman Spectroscopy.

Abstract

Tip-enhanced Raman spectra of as-grown self-assembled Ge/Si quantum dots have been observed with nano-scale spatial resolution. It is found that the Ge-Ge and Si-Ge modes in the Raman spectra were significantly enhanced only when the tip was on the Ge/Si dots. The Ge content in a single dot was estimated from the relative intensity of the Ge-Ge and Si-Ge modes. It is also found that the Si substrate peak at 520 cm-1 was shifted considerably in the neighborhood of the Ge/Si dots. This means that the Si substrate suffers stress around the dots.

247. Practical Syntheses of Neopentyl Alcohol and sec-Butyl Ethyl Ether Using Marukasol as a Solvent

Author

Yuasa, Y. and Kato, Y.

Abstract

By using Marukasol, neopentyl alcohol and sec-butyl ethyl ether have been obtained in good yields with easy operations. Thus, neopentyl alcohol was obtained from tert-butylmagnesium chloride and paraformaldehyde in 76% isolated yield with >99% purity using Marukasol as an effective extraction solvent. On the other hand, sec-butyl ethyl ether was obtained from sodium sec-butoxide with ethyl iodide in Marukasol in 67% yield with >99% purity.
