Backscattered electron

{
  "id": "MLC-T-CHM-001082",
  "term": "Backscattered electron",
  "field": "Chemistry",
  "definition": "An electron from the primary incident beam that has undergone elastic scattering within a solid sample and subsequently emerges from the surface. These electrons carry information about the atomic number and topography of the sample due to their high energy and sensitivity to material density. They are commonly used in scanning electron microscopy for compositional contrast imaging.",
