A team led by Chung Moon-seok, a physics professor at Hanyang University, has developed a machine learning-based technology capable of precisely analyzing structural changes at the nanometer level using artificial intelligence. The findings, published April 16 in
Applied Physics Reviews, suggest new possibilities for improving spectroscopy analysis without relying on expensive specialized equipment.
Potential Applications in High-Tech Industries
The technology holds promise for high-tech sectors demanding high-resolution analysis,including semiconductors,biotechnology,and advanced materials. Accurate observation and analysis of nanometer-sized material structures are crucial, as even minute changes can substantially impact performance in semiconductor processing, two-dimensional interpretation, and quantum device development.
Overcoming Limitations of Traditional Methods
Previously, high-resolution analysis required costly equipment and time-consuming experiments. To address these limitations, Chung’s team developed a machine learning model that predicts Raman spectrum by inputting Kelvin Probe Force Microscopy (KPFM) data. The model, based on a concerted neural network (CNN), reportedly improved the spatial resolution of existing Raman data to 50 nanometers.
Explainable AI Provides Insights
The study also applied explainable artificial intelligence (XAI) to quantitatively analyze how KPFM data contributes to Raman spectroscopy, going beyond simple prediction models. The analysis revealed that KPFM reflects micrometer-level electrical properties and complements Raman prediction within the AI model. These results were further validated through quantum mechanics-based density function theory (DFT) calculations.
Visualizing Stress Distribution in Nanostructures
Researchers visualized the technology by examining wrinkles in WS2 faults, a two-dimensional semiconductor material. This allowed them to precisely visualize the movement and strength of Raman Peak, which changes due to compression and tensile stress distribution. The findings demonstrated that various stresses can coexist within the same nanostructure, advancing the understanding of the physical phenomena at this scale.
Paradigm Shift in High-Resolution Analysis
“This technology represents a potential paradigm shift in high-resolution analysis,” Chung said. “It can predict and explain the structure and stress distribution of nanocytes using artificial intelligence, making it a core technology for industries requiring precision, such as semiconductors, next-generation materials, and quantum devices.”
Research Support
The research was supported by the Korea Research Foundation Innovation Research Center project and mid-sized researchers support projects. The paper,titled ‘Probing Nanoscale structural PertURBATION in WS₂ Monolayer via Explainable Artificial Intelligence,’ lists dr. as the first author and Chung as the corresponding author.
