Correlating Local Chemical and Structural Order Using Geographic Information Systems-Based Spatial Statistics
Michael Xu, Abinash Kumar, James M. LeBeau
Analysis of nanoscale short-range chemical and/or structural order via (scanning) transmission electron microscopy (S/TEM) imaging is fundamentally limited by projection of the thr…
Towards Augmented Microscopy with Reinforcement Learning-Enhanced Workflows
Michael Xu, Abinash Kumar, James M. LeBeau
Here, we report a case study implementation of reinforcement learning (RL) to automate operations in the scanning transmission electron microscopy (STEM) workflow. To do so, we des…
Antisite defects stabilized by antiphase boundaries in YFeO thin films
Abinash Kumar, Konstantin Klyukin, Shuai Ning +7
YFeO thin films are a recent addition to the family of multiferroic orthoferrites where Y\textsubscript{Fe} antisite defects and strain have been shown to introduce polar displ…
An antisite defect mechanism for room temperature ferroelectricity in orthoferrites
Shuai Ning, Abinash Kumar, Konstantin Klyukin +6
Single-phase multiferroic materials that allow the coexistence of ferroelectric and magnetic ordering above room temperature are highly desirable, motivating an ongoing search for…
Direct Imaging and Electronic Structure Modulation of Moiré Superlattices at the 2D/3D Interface
Kate Reidy, Georgios Varnavides, Joachim Dahl Thomsen +7
The atomic structure at the interface between two-dimensional (2D) and three-dimensional (3D) materials influences properties such as contact resistance, photo-response, and high-f…
Decoding the complexities of lead-based relaxor ferroelectrics
Abinash Kumar, Jonathon N. Baker, Preston C. Bowes +5
Relaxor ferroelectrics, which can exhibit exceptional electromechanical coupling are some of the most important functional materials with applications ranging from ultrasound imagi…
