Dynamic control of high-voltage actuator arrays by light-pattern projection on photoconductive switches

Herbert Shea, Amir Firouzeh, Edouard Franck Vincent Gustave Leroy

The ability to control high-voltage actuator arrays relies, to date, on expensive microelectronic processes or on individual wiring of each actuator to a single off-chip high-voltage switch. Here we present an alternative approach that uses on-chip photoco ...

Influence of Fin and Finger Number on TID Degradation of 16-nm Bulk FinFETs Irradiated to Ultrahigh Doses

Christian Enz

This article investigates the fin- and finger-number dependence of the total ionizing dose (TID) degradation in 16-nm bulk Si FinFETs at ultrahigh doses. n- and p-FinFETs designed with different numbers of fins and fingers are irradiated up to 500 Mrad(SiO ...

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, Wolfgang Amadeus Vitale, Clara-Fausta Moldovan, 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 ...
