Reconfigurable electronics based on metal-insulator transition : steep-slope switches and high frequency functions enabled by Vanadium Dioxide

Wolfgang Amadeus Vitale

The vast majority of disruptive innovations in science and technology has been originated from the discovery of a new material or the way its properties have been exploited to create novel devices and systems. New advanced nanomaterials will have a lasting ...

Electrothermal actuation of vanadium dioxide for tunable capacitors and microwave filters with integrated microheaters

Mihai Adrian Ionescu, Andreas Schueler, Clara-Fausta Moldovan, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale, Antonio Paone, Luca Petit

We report the fabrication, modeling and characterization of novel microwave tunable capacitors based on the metal-insulator transition (MIT) of Vanadium Dioxide (VO2) as a future replacement solution for microelectromechanical capacitive switches. We prese ...

Investigation of the metal-insulator transition in VO2 for Electronic Switches with Sub-1mV/Decade Steep Subthreshold Slope

Mihai Adrian Ionescu, Andreas Schueler, Josef Andreas Schuler, Clara-Fausta Moldovan, Wolfgang Amadeus Vitale, Antonio Paone

We report a thorough investigation of the electrically-induced metal-insulator transition in vanadium dioxide (VO2) for abrupt switching in 2-terminal devices (0.24 mV/dec at 25 °C, 0.38 mV/dec at 50 °C). We exploit the electrothermal actuation model based ...

Solid-gap wine-glass mode disks VB-FET resonators applied to biomass sensing

Mihai Adrian Ionescu, Mariazel de la Candelas Maqueda López, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale

The working principle of an electromechanical resonator for mass sensing applications is based on monitoring the characteristic resonance frequency downshift due to the particles attachment on the surface of the device. Solid-Gap Vibrating-Body Field Effec ...

Fabrication process and characterization of suspended graphene membranes for RF NEMS capacitive switches

Mihai Adrian Ionescu, Clara-Fausta Moldovan, Wolfgang Amadeus Vitale, Laurent Syavoch Bernard, Pankaj Sharma

The fabrication of a Nanoelectromechanical System (NEMS) capacitive switch consisting of a suspended multilayer graphene membrane, doubly clamped on a coplanar waveguide (CPW) is presented and its RF performance is evaluated. The scattering parameters are ...

Fabrication of CMOS-compatible abrupt electronic switches based on vanadium dioxide

Mihai Adrian Ionescu, Clara-Fausta Moldovan, Josef Andreas Schuler, Wolfgang Amadeus Vitale, Antonio Paone

Vanadium dioxide thin films were deposited on amorphous SiO2-coated Si substrates, by reactive magnetron sputtering at 490 °C of a pure vanadium target. The deposition parameters were optimized in order to maximize the resistivity modulation due to the met ...
