- W4387427890 abstract "Abstract Cold-source field-effect transistors (CS-FETs) have been developed to overcome the major challenge of power dissipation in modern integrated circuits. Cold metals suitable for n-type CS-FETs have been proposed as the ideal electrode to filter the high-energy electrons and break the thermal limit on subthreshold swing (SS). In this work, regarding the p-type CS-FETs, we proposed Tc X 2 and Re X 2 ( X =S, Se) as the injection source to realize the sub-thermal switching for holes. First-principles calculations unveiled the cold-metal characteristics of monolayer Tc X 2 and Re X 2 , possessing a sub-gap below the Fermi level and a decreasing DOS with energy. Quantum device simulations demonstrate Tc X 2 and Re X 2 can enable the cold source effects in WSe 2 p-type FETs, achieving steep SS of 29~38 mV/decade and high on/off ratios of (2.3~5.6)×10 7 . Moreover, multilayer ReS 2 retains the cold metal characteristic, thus ensuring similar CS-FET performances to that of the monolayer source. This work underlines the significance of cold metals for the design of p-type CS-FETs." @default.
