Abstract:

The possible geometrical structure of the PdSin(n=1—15) clusters were optimized with density-functional theory(DFT) approach at B3LYP level, based on the crystal structure analysis by particle swarm optimization(CALYPSO). The electronic properties, infrared and Raman spectrum were also studied. The calculated results indicate that the most stable structures of PdSin clusters develop from planar to three-dimen-sional structure; when n≤4, vibrational frequencies are in a range of 450—500 cm-1; when n≥5, vibrational frequencies are in a range of 50—500 cm-1, the strong peak modes are found almost to be an breathing vibration of the Si atoms.
