Meltdown of palladium nanoparticles due to prolonged hydrogen ion bombardment
چکیده انگلیسی

Nanometric crystalline particles of palladium are known to form on polycrystalline palladium under the bombardment of low-energy hydrogen ions. Mostly, the Pd particles disperse on an amorphous medium or in a matrix protruding from the target surface. Here evidence is presented that Pd nanoparticles originally present on the matrix surface are liquefied by bombarding hydrogen ions. The macroscopic target temperature for this to occur is around one-third of the melting point of Pd. This phenomenon is too unfamiliar to be described in terms of existing scientific models and an as-yet unknown process might underlie its occurrence.
