Conductance maps

Conductance maps are visual representations that show how easily electrical current flows through different parts of a material or surface at a microscopic level. They are created by scanning an area with a specialized instrument that measures the local electrical conductance at each point. These maps help scientists understand the electrical properties and surface features of materials, revealing variations such as defects, different materials, or changes in surface structure. Essentially, conductance maps provide a detailed "electrical fingerprint" of a surface, helping to analyze its composition and behavior at tiny scales.
