چکیده
The interpretation of ferroelectric domain images obtained with a piezoresponse force microscope (PFM) is discussed. The influence of an inherent experimental background on the domain contrast in PFM images (enhancement, nulling, inversion) as well as on the shape and the location of the domain boundaries are described. We present experimental results to evidence our analysis of the influence of the background on the domain contrast in PFM images.

Frontiers of Ferroelectricity
Three kinds of near-field microscopy imaging mode including SEAM (Scanning electron acoustic microscopy), PFM (Piezoresponse force microscopy) and SPAM (Scanning probe acoustic microscopy) have been developed to investigate domain structures of ferroelectric ceramics, crystals and thin films in our studies. The domain imaging mechanisms are presented individually in three imaging modes. Sub-sur...
متن کاملContrast Mechanism for Visualization of Ferroelectric Domains with Scanning Force Microscopy
Scanning force microscopy is an ideal technique for non-destructive investigation of ferroelectric domains. Application of such domains for efficient optical frequency conversion and for ultrahigh-density data storage requires μm to nm-sized domain structures. Thus the high lateral resolution offered by scanning force microscopy is highly desired. However, the mechanism causing the domain contr...
متن کاملContrast mechanism maps for piezoresponse force microscopy
Piezoresponse force microscopy (PFM) is one of the most established techniques for the observation and local modification of ferroelectric domain structures on the submicron level. Both electrostatic and electromechanical interactions contribute at the tip-surface junction in a complex manner, which has resulted in multiple controversies in the interpretation of PFM. Here we analyze the influen...
متن کاملPiezoresponse force microscopy studies of switching behavior of ferroelectric capacitors on a 100-ns time scale.
Piezoresponse force microscopy is a powerful technique for nm-scale studies but is usually limited by response time. In this Letter, we report the first direct studies of ferroelectric capacitor switching on a submicrosecond time scale. Simultaneous domain imaging and sub-mus transient current measurements establish a direct relationship between polarization P(t) and domain kinetics. Switching ...
متن کاملImaging mechanism of piezoresponse force microscopy of ferroelectric surfaces
In order to determine the origin of image contrast in piezoresponse force microscopy (PFM), analytical descriptions of the complex interactions between a small tip and ferroelectric surface are derived for several sets of limiting conditions. Image charge calculations are used to determine potential and field distributions at the tip-surface junction between a spherical tip and an anisotropic d...
