Chip Industry Week In Review


By Adam Kovac, Gregory Haley, and Liz Allan. The U.S. government released a 61-page report, titled "National Strategy on Microelectronics Research,” by the Subcommittee On Microelectronics Leadership. It provides a framework for government, industry, academia, and international allies to address four major goals. Synopsys  acquired Intrinsic ID, which develops physical unclonable func... » read more

Identification of two-dimensional layered dielectrics from first principles


Abstract "To realize effective van der Waals (vdW) transistors, vdW dielectrics are needed in addition to vdW channel materials. We study the dielectric properties of 32 exfoliable vdW materials using first principles methods. We calculate the static and optical dielectric constants and discover a large out-of-plane permittivity in GeClF, PbClF, LaOBr, and LaOCl, while the in-plane permittiv... » 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
