Visualizing the impact of quenched disorder on 2D electron Wigner solids

Researchers developed a new technique combining atomically resolved scanning tunneling microscopy with neural-quantum-state quantum Monte Carlo simulation to visualize the impact of quenched disorder on 2D electron Wigner solids. This method, published online on June 17, 2026, in Nature, establishes a framework for clearly identifying two distinct defect-induced disorder regimes. The study's findings are crucial for understanding the complex behavior of electrons in two-dimensional systems, which have implications for future electronic devices and quantum computing. The integration of advanced simulation techniques with high-resolution microscopy allows for unprecedented insights into the microscopic structure and electronic properties of these materials. This breakthrough offers a pathway to engineer materials with tailored electronic properties by controlling disorder.
