✦ Synopsis

Spherical typed Pt, Ni and Pt/Ni nanoparticles less than 50 nm in particle size were successfully obtained by pulsed wire explosion in D.I. water. The Pt nanoparticles exhibited high purity, but the Ni nanoparticles exhibited a partial and very thin oxide layer. It was confirmed that the obtained Pt/Ni nanoparticles consisted of Pt and Ni nanoparticles as well as PtNi composite nanoparticles of solid solution type.

When using Schottky barrier diodes (SBDs) on silicon (Si) to study the thermal stability of radiation-induced defects, point defects injection into the silicon substrate can occur at temperatures where silicidation occurs. These injected point defects can react with the radiation-induced defects and
