Localized deposition of metallic molybdenum particles in ambient air using atmospheric-pressure microplasma

The authors report the details of the deposition process and the unique structure of metallic Mo particles obtained under specific conditions. Results indicated that the surface of the as-deposited particles was oxidized, but the inside of the deposit is mostly metallic Mo. The microstructure of the star-shaped Mo particles was characterized with TEM and TED. The analysis of the complicated TED pattern indicated that the star-shaped Mo particles are five-fold symmetrical multiply twinned particle.
