Electroless nickel-high-phosphorus Ni–P plating is used as substrate coating in the electronic component technology. The ability to minimize pores formation in solder joints and the wettability of the Ni–P layer remain points of investigation. Th

UV and visible multiphoton dissociation of Al(CH3)3 (m-TMA) have been investigated by mass spectrometry detection of ionic photofragments. The relative abundances of Al+ and C+ ions and the law of production were monitored as a function of photolysis

We have studied the soft laser sputtering of (100)GaAlAs with 337 nm photons, starting from the threshold for particle emission (a few tens mJ/cm 2 ) up to about 300 mJ / cm 2 . Atoms and molecules sputtered from the irradiated surface are detected,

We have studied the soft laser sputtering of (100)GaAs with 337 nm photons, starting from the threshold for particle emission (a few tens of mJ/cm2) to some 300 mJ/cm2 fluences. Atoms and molecules sputtered from the irradiated surface are detected,
