Ferroelectric or non-ferroelectric: Why so many materials exhibit “ferroelectricity” on the nanoscale [PDF]

Applied Physics Reviews, 2017
Ferroelectric materials have remained one of the major focal points of condensed matter physics and materials science for over 50 years. In the last 20 years, the development of voltage-modulated scanning probe microscopy techniques, exemplified by Piezoresponse force microscopy (PFM) and associated time- and voltage spectroscopies, opened a pathway to

Ferroelectric Electron Holography [PDF]

Microscopy and Microanalysis, 2002
Ferroelectrics are increasingly important as materials in semiconductor technology, e.g. for building non-volatile memory chips. For optimisation of the properties of such devices, there is an urgent need for methods, which analyse the ferroelectric properties at nanometer scale. Furthermore, the basic understanding of the interaction of ferroelectrics
