“…Since the polarization is almost exclusively in-plane oriented in most of the images, the vertical PFM images give mainly contrast along the [010] axis (due to the cantilever buckling effect). [31][32][33] Compar- ison of lateral and vertical mode images taken in the same area clearly confirms presence of about 0.5-1 micron size "coarse domains" formed by regular nanodomain a/a/a/a twinned areas with about 20 nm wide a-domain stripes with polarization oriented alternatively along…”

“…124 Furthermore, buckling contributions to the VPFM signal as well as topographical cross-talk strongly encourage the practice of angle-resolved PFM to discriminate true contributions of the ferroelectric polarisation. 60,125 An LPFM signal that is piezoelectric in nature can however be observed in samples devoid of in-plane polarisation, at the position of 180 • domain walls, as shown in Fig. 3.…”

Piezoresponse force microscopy (PFM) probes the mechanical deformation of a sample in response to an electric field applied with the tip of an atomic force microscope. Originally developed more than two decades ago to study ferroelectric materials, this technique has since been used to probe electromechanical functionality in a wide range of piezoelectric materials including organic and biological systems. PFM has also been demonstrated as a useful tool to detect mechanical strain originating from electrical phenomena in nonpiezoelectric materials. Paralleling advances in analytical and numerical modelling, many technical improvements have been made in the last decade: switching spectroscopy PFM allows the polarisation switching properties of ferroelectrics to be resolved in real space with nanometric resolution, while dual ac resonance tracking and band excitation PFM have been used to improve the signal-to-noise ratio. In turn, these advances have led to increasingly large multidimensional data sets containing more complete information on the properties of the sample studied. In this review, PFM operation and calibration are described, and recent advances in the characterisation of electromechanical coupling using PFM are presented. The breadth of the systems covered highlights the versatility and wide applicability of PFM in fields as diverse as materials engineering and nanomedicine. In each of these fields, combining PFM with complementary techniques is key to develop future insight into the intrinsic properties of the materials as well as for device applications.

“…However, despite the need to understand polarization orientations, experimental methods to resolve the inplane and out-of-plane polarization in ferroelectric or multiferroic thin films are not well established. Piezoresponse force microscopy (PFM) measures electromechanical responses which can be linked to local polarizations described by the piezoelectric and electrostriction constant tensors [43][44][45]. This approach allows domain structures to be successfully mapped with excellent resolution (10 nm lateral resolution and displacements of sub-pm) [46].…”

The human brain (volume=1200cm3) consumes 20W and is capable of performing > 10^16 operations/s. Current supercomputer technology has reached 1015 operations/s, yet it requires 1500m^3 and 3MW, giving the brain a 10^12 advantage in operations/s/W/cm^3. Thus, to reach exascale computation, two achievements are required: 1) improved understanding of computation in biological tissue, and 2) a paradigm shift towards neuromorphic computing where hardware circuits mimic properties of neural tissue. To address 1), we will interrogate corticostriatal networks in mouse brain tissue slices, specifically with regard to their frequency filtering capabilities as a function of input stimulus. To address 2), we will instantiate biological computing characteristics such as multi-bit storage into hardware devices with future computational and memory applications. Resistive memory devices will be modeled, designed, and fabricated in the MESA facility in consultation with our internal and external collaborators. (1463), and Robert Leland (1000) were crucial in helping to steer this effort in the larger context of Sandia's national security missions.

We also extend our gratitude to Michael Rye and Bonnie McKenzie for focused ion beam serial sectioning and scanning electron microscopy.
