| 内容記述 | In this study, niobium trisulfide (NbS3), a needle-like crystal, was prepared and observed by photoelectron spectroscopy for the purpose of clarifying the electronic state, one-dimensional property, and polytype. As a result, the spectrum of Nb could be fitted with an asymmetrical peak, but the spectrum of S could be fitted with a symmetrical peak, indicating that only Nb is involved in electrical conduction. In addition, it was found from the analysis of valence band's spectrum that NbS3 prepared under this condition is a one-dimensional substance with the Tomonaga-Luttinger liquid properties, and not an insulator. From the analysis of S 2s spectrum and Nb 3s spectrum, it was found that the NbS3 sample was composed of Nb4+ and S2－ ion. By comparing the results at room temperature with the results at 353 K, it was found that there is no noticeable difference in the shape of the peaks, indicating that the sample does not exhibit the charge-density-wave transfer expected at 353 K. Regarding the polytype of the sample, NbS3-V is considered to be the closest one because of our preparation method, which involves heating Nb and S at about 710℃ in the presence of a slightly excess amount of sulfur, and the fact that no gap was observed in our mesurements. | |||||||||||
