jagar2 / Revealing Ferroelectric Switching Character Using Deep Recurrent Neural NetworksThe ability to manipulate domains and domain walls underpins function in a range of next-generation applications of ferroelectrics. While there have been demonstrations of controlled nanoscale manipulation of domain structures to drive emergent properties, such approaches lack an internal feedback loop required for automation. Here, using a deep sequence-to-sequence autoencoder we automate the extraction of features of nanoscale ferroelectric switching from multichannel hyperspectral band-excitation piezoresponse force microscopy of tensile-strained PbZr0.2Ti0.8O3 with a hierarchical domain structure. Using this approach, we identify characteristic behavior in the piezoresponse and cantilever resonance hysteresis loops, which allows for the classification and quantification of nanoscale-switching mechanisms. Specifically, we are able to identify elastic hardening events which are associated with the nucleation and growth of charged domain walls. This work demonstrates the efficacy of unsupervised neural networks in learning features of the physical response of a material from nanoscale multichannel hyperspectral imagery and provides new capabilities in leveraging multimodal in operando spectroscopies and automated control for the manipulation of nanoscale structures in materials.

lnlp / FramI2CFramI2C is an Arduino library for FRAM (F-FRAM, Ferroelectric RAM) non-volatile memory chips with I2C interface. Supports most common Cypress and Fujitsu I2C FRAM chips with densities of 4, 16, 64, 128, 256, 512, and 1024 kilobits (kb). Provides simple, easy to use read() and write() methods for reading/writing integral and floating point types (uses automatic type inference and byte conversion), readBytes() and writeBytes() for reading/writing larger amounts of data as byte array, and fill() to fill or clear a range of FRAM memory.

huiihao / SpiralWe identify a ferroelectric topological structure, termed "dipole spiral," which exhibits a giant intrinsic piezoelectric response (>320 pC/N). This helical structure, primarily stabilized by entropy and possessing a rotational zero-energy mode, unlocks new possibilities for exploring chiral phonon dynamics and dipolar DM-like interactions.
