From Tacit Expertise to AI-Ready Scientific Data and Knowledge Corpora

Luke Schneider, Ganesh Narasimha, Sumner B. Harris, Ralph Bulanadi et autres

Artificial intelligence for domain science relies on large, well-structured training corpora that integrate experimental data with explicit contextual knowledge and the tacit expertise underlying scientific decisions. However, scientific information remains fragmented across publications. In particular, the information regarding practical reasoning, assumptions, failed …

Automated Three-Dimensional Piezoresponse Force Microscopy for Polarization-Vector Mapping at the Nanoscale

Ralph Bulanadi, Martí Checa, Michelle Wang, Franck Rothen et autres

Abstract The functional properties of ferroelectric materials are strongly influenced by their polarization orientation; as such, precise characterization of polarization vectors is important to ferroelectrics research. Here, we develop a fully automated three-dimensional piezoresponse force microscopy (Auto-3DPFM) technique, which integrates all essential …

Accelerating Structure–Property Relationship Discovery with Multimodal Machine Learning and Self-Driving Microscopy

Jiawei Gong, Danqing Ma, Ralph Bulanadi, R. G. Moore et autres

Microscopy combined with local spectroscopy is widely used to correlate nanoscale structure with functional properties in materials, but conventional measurements rely heavily on human-selected sampling locations and predefined targets, limiting data set diversity and the potential for discovery. Here, we present a …

Dynamics of Null and Electrostatic Blind Spots for Quantitative PFM

Martí Checa, Holland Swicegood, Rubén Millán‐Solsona, Ralph Bulanadi et autres

Piezoresponse force microscopy is a cornerstone technique for probing nanoscale electromechanical phenomena, yet quantitative and in some cases qualitative interpretation remains hindered by parasitic electrostatic forces coupled through cantilever dynamics. Recent approaches aim to suppress these artifacts by operating at resonance defined …

AEcroscopyWave: Towards Self-Driving Characterization Platforms for Agentic AI

Yongtao Liu, Jawad Chowdhury, Ganesh Narasimha, Ralph Bulanadi et autres

The characterization of electronic materials has traditionally been stratified into two distinct regimens: industry-scale automated systems to inspect materials for defects and ensure quality (such as in the semiconductor industry), and highly customized, operator-driven systems requiring human experts. The former offers high …

Self-Driving Scanning Probe Microscopy: From Acceleration to Discovery and Manipulation

Ganesh Narasimha, Ralph Bulanadi, Jawad Chowdhury, Rama Vasudevan et autres

Scanning probe microscopy offers a powerful suite of techniques for investigating meso-, micro- and nanoscale phenomena ─ enabling the exploration of advanced materials, heterostructures, quantum materials, as well as providing insight into surface energetics and reactions. Additional spectroscopic capabilities combined with multimodal …

Scan‐Path‐ and Initial‐State‐Dependent Superdomain Switching in (111)‐Oriented PZT

Rama Krishnan Vasudevan, Laveeza Ahmad, Bharat Pant, Ralph Bulanadi et autres

ABSTRACT Polarization switching in ferroelectric materials arises from the collective evolution of complex domain hierarchies, yet deterministic control over these processes remains challenging. Here, we investigate scan‐path‐ and initial‐state‐dependent switching in epitaxial (111)‐oriented PbZr 0.2 Ti 0.8 O 3 thin films using …

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides

Mohammad Moein Seyfouri, Oliver Paull, Ralph Bulanadi, Yasuhiro Sakamoto et autres

ABSTRACT A polar oxide on the brink displays enhanced electromechanical response, classically from a combination of phase competition and domain wall motion. In epitaxial thin films, however, such enhancement is widely suppressed by substrate clamping, which immobilizes structural interfaces. Here, we show …
