Researchers at Cornell University and Columbia University have developed a way to stack two-dimensional semiconductors and trap electrons in a repeating pattern that forms a specific and long-hypothesized crystal. The team also devised a new optical sensing technique that enabled them to observe numerous electron crystals with different crystal symmetries.
