The high-mobility bended n-channel silicon nanowire transistor

Mihai Adrian Ionescu, Didier Bouvet, Kirsten Emilie Moselund, Vincent Pott, Luca De Michielis, Mohammad Najmzadeh

This work demonstrates a method for incorporating strain in silicon nanowire gate-all-around (GAA) n-MOSFETs by oxidation-induced bending of the nanowire channel and reports on the resulting improvement in device performance. The variation in strain measur ...

Capacitor-less memory and abrupt switch based on hysteresis characteristics in punch-through impact ionization mos transistor (PI-MOS)

Maher Kayal, Mihai Adrian Ionescu, Kirsten Emilie Moselund, Vincent Pott

The present invention exploits the impact ionization induced by drain voltage increase and the onset of a bipolar parasitic in an Omega-gate field effect metal oxide insulator transistor (called PI-MOS), in order to obtain a memory effect and abrupt curren ...

Non-hysteretic punchthrough impact ionization MOS (PIMOS) transistor: Application to abrupt inverter and NDR circuits

Mihai Adrian Ionescu, Kirsten Emilie Moselund, Vincent Pott

The recently proposed PIMOS transistor can offer, by appropriate operation, non-hysteretic abrupt off-on transitions due to impact ionization if the action of its parasitic bipolar transistor is minimized. This work proposes non-hysteretic abrupt inverter ...

Hysteretic inverter-on-a-body-tied-wire based on less-than-10mV/decade abrupt punch-through impact ionization MOS (PIMOS) switch

Mihai Adrian Ionescu, Didier Bouvet, Kirsten Emilie Moselund, Vincent Pott

This work reports for the first time on a cascadable NMOS inverter based on punch-through impact ionization MOSFET (PIMOS) integrated on a single body-tied silicon wire. The PIMOS device acts as a single-transistor-latch and shows abrupt current switching ...
