In this work we develop surface-micromachined RF MEMS switches in III-V technology making use of materials which can be alternative to the ones commonly used. In this way, some technological constraints concerning RF MEMS reliability can be overcome. Specifically, we evaluate the potential of tantalum nitride (TaN) and tantalum pentoxide (Ta2O5) to be used for the switches actuation pads and dielectric...
The optical response at room temperature of ZnO nanostructures, grown by controlled vapour phase deposition, to low concentrations of NO2 gas mixed in dry-air has been investigated. In particular the quenching in the emission signal, due to the interactions between oxidizing gas molecules and sample surface, has been monitored in excitonic and defect band, as a function of NO2 gas concentration. The...
