The ultimate limit of this concept will depend on the ferroelectric limit (synonymous superparaelectric limit), i.e. the size limit below which the ferroelectricity is quenched. While there are clear indications that 2D ferroelectric oxide films may sustain their ferroelectric polarization below 4 nm in thickness (Tybell T, Ahn C H and Triscone J M 1999 Appl. Phys. Lett. 75 856), the limit will be quite different for isolated 3D nanostructures (nanograins, nanoclusters).To investigate scaling effects of ferroelectric nanograins on Si wafers, we studied PbTiO3 (PTO) and Pb(ZrxTi1-x)O-3 grown by a self-assembly chemical solution deposition method. Preparing highly diluted precursor solutions we achieved single separated ferroelectric grains with grain sizes ranging from 200 nm down to less than 20 nm.For grains smaller than 20 nm, no piezoresponse was observed and we suppose this could be due to the transition from the ferroelectric to the paraelectric phase which has no spontaneous polarization. Recent calculations (Zhong W L, Wang Y G, Zhang P L and Qu B D 1994 Phys. Rev. B 50 698) and experiments (Jiang B, Peng J L, Zhong W L and Bursill L A 2000 J. Appl. Phys. 87 3462) showed that the ferroelectricity of fine ferroelectric particles decrease with decreasing particle size. From these experiments the extrapolated critical size of PTO particles was found to be around 4.2-20 nm. 000030192 536__ $$0G:(DE-Juel1)FUEK252$$2G:(DE-HGF)$$aMaterialien, Prozesse und Bauelemente für die Mikro- und Nanoelektronik$$cI01$$x0 000030192 588__ $$aDataset connected to Web of Science 000030192 650_7 $$2WoSType$$aJ 000030192 7001_ $$0P:(DE-HGF)0$$aSchneller, T.$$b1 000030192 7001_ $$0P:(DE-Juel1)VDB2799$$aSzot, K.$$b2$$uFZJ 000030192 7001_ $$0P:(DE-Juel1)131022$$aWaser, R.$$b3$$uFZJ 000030192 773__ $$0PERI:(DE-600)1362365-5$$a10.1088/0957-4484/14/2/328$$gVol. 14, p. 250 - 253$$p250 - 253$$q14<250 - 253$$tNanotechnology$$v14$$x0957-4484$$y2003 000030192 8567_ $$uhttp://hdl.handle.net/2128/1234$$uhttp://dx.doi.org/10.1088/0957-4484/14/2/328 000030192 8564_ $$uhttps://juser.fz-juelich.de/record/30192/files/27678.pdf$$yOpenAccess 000030192 8564_ $$uhttps://juser.fz-juelich.de/record/30192/files/27678.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000030192 8564_ $$uhttps://juser.fz-juelich.de/record/30192/files/27678.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000030192 8564_ $$uhttps://juser.fz-juelich.de/record/30192/files/27678.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000030192 909CO $$ooai:juser.fz-juelich.de:30192$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000030192 9131_ $$0G:(DE-Juel1)FUEK252$$bInformation$$kI01$$lInformationstechnologie mit nanoelektronischen Systemen$$vMaterialien, Prozesse und Bauelemente für die Mikro- und Nanoelektronik$$x0 000030192 9141_ $$y2003 000030192 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000030192 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000030192 9201_ $$0I:(DE-Juel1)VDB35$$d31.12.2003$$gIFF$$kIFF-EKM$$lElektrokeramische Materialien$$x0 000030192 970__ $$aVDB:(DE-Juel1)27678 000030192 980__ $$aVDB 000030192 980__ $$aJUWEL 000030192 980__ $$aConvertedRecord 000030192 980__ $$ajournal 000030192 980__ $$aI:(DE-Juel1)PGI-7-20110106 000030192 980__ $$aUNRESTRICTED 000030192 980__ $$aFullTexts 000030192 9801_ $$aFullTexts 000030192 981__ $$aI:(DE-Juel1)PGI-7-20110106
