Single-Crystal High-κ Dielectric Enables Low-Power 2D CFETs (NUS et al.)

Researchers led by the National University of Singapore  and Nexstrom published “Low-power 2D CFETs using single-crystal high-κ dielectrics.”

Abstract Excerpt:
“Here we demonstrate that a wafer-scale, transferable, single-crystal anatase titanium dioxide dielectric can be van der Waals integrated with 2D transition metal dichalcogenides. The obtained pristine 2D-dielectric interface enables subthreshold swing close to the thermal limit, record-low hysteresis and well-matched transfer characteristics for both n- and p-type enhancement-mode field-effect transistors. Building on this, we demonstrate complementary field-effect transistors, whose inverters achieve high voltage gain and large noise margins with subpicowatt static power consumption. These results highlight the promise of 2D semiconductors for ultra-low-power operation.”
