STEM Characterization of Metal Clusters In/On Oxides
Mehraeen, Shareghe
Dispersed metal clusters in or on a support matrix are key phenomena in many technological fields. Two widely used examples of them are supported-metal clusters in heterogeneous catalysts and transition metal clusters in diluted magnetic semiconductors (DMS). The catalytic activity and selectivity of catalysts depend sensitively on structure parameters like particles size and shape. With the same analogy, the magnetic properties of DMS oxides ...
