Abstract

Niobium carbide nanocrystals of ~1:1 stoichiometry have recently been observed for particle sizes ranging fromNb4C4toNb50C50. Infrared (IR) spectroscopic measurements show that a new band of IR vibrational modes appears with increasing particle size atNb9C9. Using density-functional theory, we show that the vibrational modes in the new band involve structural features present only in nanocrystals with three or more atomic layers in every direction. TheNb9C9nanocrystal is right at this structural threshold.
