IMPACT OF OXIDE MATERIALS ON SELF-HEATING EFFECT AND SUBTHRESHOLD SLOPE IN 2D MoS2-BASED MOSFET
In this paper self-heating effect (SHE) and subthreshold slope (SS) at different gate and back oxide materials in 2D MoS2-based MOSFET were considered through simulation. In this study, the Al2O3 and HfO2 oxides were selected as gate oxide materials and SiO2 and HfO2 as back oxide (BOX) materials....
