An Open-Source Hardware and Software Toolkit to Enable Agentic RHEED-Guided Thin-Film Synthesis
Asraful Haque, Christopher M. Rouleau, Rama K. Vasudevan +1
Reflection high-energy electron diffraction (RHEED) provides rich information about evolving surfaces during thin-film growth, but non-automated, operator-dependent alignment and f…
AEcroscopyWave: Towards Self-Driving Characterization Platforms for Agentic AI
Yongtao Liu, Jawad Chowdhury, Ganesh Narasimha +8
The characterization of electronic materials has traditionally been stratified into two distinct regimens: industry-scale automated systems to inspect materials for defects and ens…
Large Pyroelectric Enhancement in Freestanding Epitaxial BaTiO3 Membranes on Si
Ajay Kumar, Asraful Haque, Shubham Kumar Parate +5
Ferroelectric membranes transferred onto arbitrary substrates provide reduced mechanical clamping at the interfaces that can diminish the effective polarization-rotation barrier of…
Human-AI collaborative autonomous synthesis with pulsed laser deposition for remote epitaxy
Asraful Haque, Daniel T. Yimam, Jawad Chowdhury +10
Autonomous laboratories typically rely on data-driven decision-making, occasionally with human-in-the-loop oversight to inject domain expertise. Fully leveraging AI agents, however…
A facile vector substrate platform via BaTiO3 membrane transfer enables high quality solution processed epitaxial PZT on silicon
Asraful Haque, Antony Jeyaseelan, Shubham Kumar Parate +2
