Experimental Evidence of Ferroelectric Negative Capacitance in Nanoscale Heterostructures [PDF]
, 2011 We report a proof-of-concept demonstration of negative capacitance effect in a nanoscale ferroelectric-dielectric heterostructure. In a bilayer of ferroelectric, Pb(Zr0.2Ti0.8)O3 and dielectric, SrTiO3, the composite capacitance was observed to be larger
