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, Antonio Paone, Clara-Fausta Moldovan, Wolfgang Amadeus Vitale

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 ...

Temperature-dependent multiangle FTIR NIR-MIR ellipsometry of thermochromic VO2 and V1-xWxO2 films

Rosendo Sanjines, Andreas Schueler, Antonio Paone

VO2 and W-doped VO2 thin films were prepared by Radio Frequency (RF) reactive magnetron sputtering using V-metal target. The amount of W doping was quantified by Rutherford Backscattering Spectrometry (RBS). The optical constants of VO2 and V1-xWxO2 films ...

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

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

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 ...
