Formation of Sn/Ag/C Nanoalloy Through Laser Ablation of Ag Target and Simultaneous Decomposition of TMT in the Gas Phase

Original language description

Increasing environmental and health concerns over the toxicity of lead-based solders have provided an inevitable driving force for the development of lead free solders. The Sn-Ag alloys are widely considered as a promising alternative due to higher strength and superior resistance to creep and thermal fatigue. We have examined a novel approach to gas-phase deposition of nanosized Sn-Ag alloys embedded in a carbonaceous phase based on IR laser ablation of Ag in a plume (dielectric breakdown) of tetramethyltin (TMT). In this approach, Ag nanoparticles are propelled from the target and mixed with Sn clusters produced in the gas phase by the decomposition of TMT. The resulting Sn/Ag structures are during their formation subject to heating and subsequent cooling within some ms. The decomposing TMT, serving as a carbon source, may provide additional stabilization of these metastable structures. We obtained thin Sn-Ag-C films that were characterized by scanning electron microscopy (SEM), Rama
