Transition-metal nitride halide dielectrics for transition-metal dichalcogenide transistors [PDF]

open access: yesNanoscale, 2022
Using first-principles calculations, we investigate six transition-metal nitride halides as potential vdW dielectrics for transition metal dichalcogenide channel transistors. We identify the best combinations for the p-MOS transistor technology.
