Germanium Negative Capacitance Field Effect Transistors: Impacts of Zr Composition in Hf1−x Zr x O2
Nanoscale Research Letters, 2019 Germanium (Ge) negative capacitance field-effect transistors (NCFETs) with various Zr compositions in Hf1−x Zr x O2 (x = 0.33, 0.48, and 0.67) are fabricated and characterized. For each Zr composition, the NCFET exhibits the sudden drop in some points of
