Tunnel-FETs are studied in a mixed device/circuit simulation environment. Model parameters calibrated on experimental DC as well as pulsed characterizations are then used for 6T SRAM cells investigation. Issues concerning fabricated devices, as the ambipolarity and the uni-directionality, are addressed at both device and circuit levels. Our results suggest that ambipolarity needs to be solved through device engineering and/or fabrication process improvements, while issues related to uni-directionality may be mitigated with a proper circuit design.

Abstract
Tunnel-FETs are studied in a mixed device/circuit simulation environment. Model parameters calibrated on experimental DC as well as pulsed characterizations are then used for 6T SRAM cells investigation. Issues concerning fabricated devices, as the ambipolarity and the uni-directionality, are addressed at both device and circuit levels. Our results suggest that ambipolarity needs to be solved through device engineering and/or fabrication process improvements, while issues related to uni-directionality may be mitigated with a proper circuit design.File in questo prodotto:
