Popis: | For the first time, we successfully demonstrated the dopant-free HfO2 negative capacitance (NC) transistor featuring a low gate-overdrive voltage and a nearly hysteresis-free sub-40 mV/dec swing. These excellent performances can be ascribed to the reduction of the monoclinic phase suppressed with the thickness scaling and gate stress engineering favorably rearranging oxygen vacancies to boost orthorhombic phase transition. The highly scalable and dopant-free NC transistor shows the potential for the application of advanced CMOS technology. |
