• dried with synthetic air. Gold nanoparticles have been deposited by RF magnetron sputtering (70 W Ar plasma for 5 s at room temperature, pressure 5 × 10−3 mbar) on the substrate, as they will act as catalyst for the nanowire growth. This technique was very easy and straightforward to use and allowed a

• alumina substrates [24]. Samples have been first cleaned in acetone using ultrasonic bath for 10 min and then dried with synthetic air. Then, a thin layer of metallic Cu has been deposited on samples by RF magnetron sputtering (50 W Ar plasma at room temperature, pressure 5 × 10−3 mbar, thickness 1 μm

• , with an argon flow of 10 sccm (30 min deposition). Afterwards, copper oxide nanowires were synthesized by thermal oxidation. Copper metallic film was deposited via RF magnetron sputtering, as described before, using a 50 W argon plasma at room temperature (thickness 2 µm, 5 × 10−3 mbar pressure

• frequency (RF) magnetron sputtering using 2’’ diameter planar targets with 99.95% purity. Three sets of pure Pd samples were prepared with constant sputtering power of 60 W at a working gas pressure (Ar) of 0.005 mbar at room temperature. Pd films of 1 µm nominal thickness were grown in 100 steps of 10 nm

• interacted with residual oxygen to give ZnO nanowires [13]. The stabilised samples were then provided by interdigitated Pt electrodes deposited by RF magnetron sputtering, while on the back side a Pt meander was deposited to act as heater (by Joule effect) and temperature sensor.
