Crater depth

  "id": "MLC-T-CHM-002662",
  "term": "Crater depth",
  "field": "Chemistry",
  "definition": "The depth of a sputter crater averaged over the region that supplies the measured signal, not the maximum depth of the whole crater. It is measured after the experiment with a stylus profilometer, an interferometric microscope or atomic force microscopy, and dividing it by the sputtering time gives the average sputter rate that converts a depth profile from time to depth.",
