A newly refined near-field optical imaging method is offering researchers a clearer look at low-dimensional materials like graphene and carbon nanotubes. By tuning into fifth-order optical signals at infrared wavelengths, the technique minimizes background interference and enhances image contrast, revealing nanoscale structures that traditional approaches often miss.Zooming Into the Nanoworld: How High-Order Signals Clarify the Invisible
