geometry that we call surface X-rayradiolysis. In this procedure, an X-ray beam produced by a synchrotron beamline intercepts the surface of an aqueous metal-ion solution covered by a Langmuir monolayer at an angle of incidence below the critical angle for total internal reflection. Underneath the organic
, results in a second growth regime of silver nanocrystals. Here the formation of the oriented thin layer is followed by the appearance of a 3D powder of silver clusters.

Formation of metal nanoclusters and
thickness of the formed layer (here, 4.5 nm thick) created with this process is determined by the penetration depth of the X-ray evanescent wave [4]. Hence, we termed this method surface X-rayradiolysis. Based on the analysis of the intensity and the shape of the diffraction peaks that emerge in the
