Some Insights Into the Process of E-beam Generation of Metal Nanoparticles From Binary Metal Hydride and Azide Precursors

Abstract

AbstractExposure of micron-sized particles of inorganic metal hydrides and azides to an intense electron beam within a transmission electron microscope results in melting followed by accelerated decomposition. The energy density localized in the specimen is considerable - arguably from one of the most intense energy deposition sources available. The induced effects have been evaluated using electron beam theory and it is concluded that, to a first approximation, the phenomena are attributable to extremely rapid heating. Criteria for the use of this technique to other possible systems are identified and future experiments applying this unique technique to other materials systems are proposed.
