| Título: | Cds plume composition and dynamics of neutral species after Ablation with 532 nm laser light (ptu-96) |
Autor: | Álvarez Ruiz, J.; López, Marien; de Nalda, R. CSIC ORCID; Martín Muñoz, Margarita CSIC | Fecha de publicación: | 24-sep-2007 | Citación: | 9th International Conference on Laser Ablation (2007) | Resumen: | CdS pellets were ablated with 532nm laser light (fluence of 0,5J/cm2) and the neutral species in the plume were investigated using a TOF mass spectrometer. Stoichiometric (CdS)n and CdnSn+m (m=1,2,3) clusters up to n = 13 were identified in the mass spectra. The dynamics of neutral S, S2, Cd and Cd2 were studied at different positions in the plume, showing mean velocities of 900 m/s at 4 mm from the surface up to 1500 m/s at 12 mm. This observed acceleration indicates that collisions between species are frequent in that region of the plume, pointing to an adiabatic expansion. | Descripción: | Trabajo presentado en el 9th International Conference on Laser Ablation, celebrado en Tenerife (España) del 27 de septiembre de 2007. | URI: | http://hdl.handle.net/10261/258465 |
