Valdés Física, Astronomía y Matemáticas Ion Scattering Atomic Force Microscopy Self supported thin films We present a description of the effect of the surface roughness on the energy straggling associated to theenergy loss distributions of protons transmitted through a self supported metallic thin foil. For this purpose weprepared a polycrystalline gold thin films using the standard sputtering method with different deposition rates.The statistics of the surface height distribution induced in these thin films were determined using Atomic ForceMicroscopy. The measured surface roughness allowed us to quantify the ion energy loss straggling in thesesamples for different deposition parameters and as a function of the incident ion energy. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436542 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36 |
