The atmospheric pressure carbon arc in inert gases is an important method for the production of nanomaterials [1]. Typical nanosynthesis arcs operate in a dc mode between a graphite anode, which is consumed, and a cathode which can be made from either graphite or a lower melting point material [2]. In spite of many studies, the basic physical processes in this discharge such as cathode electron...

We report single-step vacuum growth of stoichiometric superconducting thin films of MgB2, using AASC’s cathodic arc deposition process. Energetic condensation using cathodic arcs produces non-equilibrium fast ions (~50-100eV) that allow growth modes on relatively low temperature substrates. We have demonstrated MgB2 films with Tc of 34K by depositing at 275 °C in a single step, from a stoichiom...

A room temperature cathodic arc deposition technique is used to produce high-mobility ZnO thin films for low voltage thin-film transistors (TFTs) and digital logic inverters. All-oxide, fully transparent devices are fabricated on alkali-free glass and flexible polyimide foil, exhibiting high performance. This provides a practical materials platform for the low-temperature fabrication of all-oxi...
