The neutral P_n clusters are even-numbered with local abundance maxima at n = 10 and 14, while the cationic and anionic clusters are preferentially odd-numbered with (P_7)+, (P_21)+, and (P_17)- being the most abundant ions. The dominance of the magic clusters is more pronounced at 337-nm ablation that is explained by efficient direct ejection of their building blocks under these conditions. Nanocrystalline phosphorus films have been produced by PLA in ambient helium gas. | | Source: | arXiv, cond-mat/0404092 | | Services: | Forum | Review | PDF | Favorites | |
