The proposed model is applicable for both 2-component suppressor and accelerator and 1-component suppressor only Cu plating chemistries.Aug 15, 1995 Femtosecond-pulse laser desorption is a process in which desorption is driven by a subpicosecond temperature pulse of order 5000 K in the substrate-adsorbate electron system, whose energy is transferred into the adsorbate center-of-mass degrees of freedom by a direct coupling mechanism. We present a systematic theoretical treatment of this coupling process in the language
