Abstract View references (12) A microelectromechanical system (MEMS) entirely made of crystalline oxides is presented. A suspended SrTiO3 (001) microcantilever is employed as flexible substrate for the deposition of epitaxial transition-metal oxide films. A strain-generator device for epitaxial oxide films can be fabricated. Strain at surface...

We report on the fabrication, mechanical characterization and electrostatic actuation of dielectric STO(0 0 1) thin film microcantilevers (MCs). Finite element analysis (FEA) is used for mechanical analysis and for calculating the distribution and the magnitude of the dielectric forces on the actual devices. The actuation of insulating oxide...

Two-terminal multistate memory elements based on VO2/TiO2 thin film microcantilevers are reported. Volatile and non-volatile multiple resistance states are programmed by current pulses at temperatures within the hysteretic region of the metal-insulator transition of VO2. The memory mechanism is based on current-induced creation of metallic...

This work shows one of the activity of the group in the framework of the HOLMES project for direct neutrino mass search. Starting from Ho oxide and working at high temperature, it is possible to obtain the deposition of a metal Ho film which is necessary for the implantation into cryogenic detectors. A simulation has been developed to...

Titanium dioxide (TiO2) thin films were prepared by means of Anodic Spark Deposition (ASD) from thin and flat metallic titanium (Ti) films pre-deposited on high quality quartz slides by electron beam evaporation. AFM analysis indicates the formation of uniform mesoporous layers and a definite increase (about 50%) of the film thickness upon...

The neutrino mass experiment MARE is presently focusing on the feasibility study of electron capture decaying isotope 163 Ho, as an alternative approach to the well investigated 187 Re beta decaying isotope. 163 Ho, which undergoes a very low Q value decay with about 4500 years half life, gives the advantages of using very low mass metallic...
