The results obtained are analyzed and compared with those obtained for the crystal and planar ribbon structures of NbS3. The formation of NbS3 ring structures leads to a considerable increase in the density of Nb 4d states at the Fermi level. The simulation of the behavior of the ring structures in the temperature range T= 0–700 K demonstrates that the Mobius strip has a lower thermal stability as compared to the NbS3 ring Полный текст |
