Pulsed laser ablation and deposition of semiconducting thin films : characterization of transient species

Abstract A study of laser-induced production and mass spectrometric analysis of ionized clusters from powder mixtures of the Group VI elements S, Se and Te and Cr, Fe, Ni, Cu, Ag, Zn, In and Cd is discussed. The binary systems Li 2 S, FeS, Ni 2 S, Ag 2 S, Ag 2 Te, ZnSe, CdS, CdSe and CdTe have also been investigated. The results show the formation of sequences of ionized products from laser ablation. Their relative stabilities are correlated to structure and reaction kinetics parameters.
