New Materials Open Door To New Devices

Integrating 2D materials into conventional semiconductor manufacturing processes may be one of the more radical changes in the chip industry’s history. While there is pain and suffering associated with the introduction of any new materials in semiconductor manufacturing, transition metal dichalcogenides (TMDs) support a variety of new device concepts, including BEOL transistors and single-... » read more

Transition-Metal Nitride Halide Dielectrics for Transition-Metal Dichalcogenide Transistors

Abstract "Using first-principles calculations, we investigate six transition-metal nitride halides (TMNHs): HfNBr, HfNCl, TiNBr, TiNCl, ZrNBr, and ZrNCl as potential van der Waals (vdW) dielectrics for transition metal dichalcogenide (TMD) channel transistors. We calculate the exfoliation energies and bulk phonon energies and find that the six TMNHs are exfoliable and thermodynamically stabl... » read more
