Photoelectrochemical etching

  "id": "MLC-T-CHM-008856",
  "term": "Photoelectrochemical etching",
  "field": "Chemistry",
  "definition": "A process where a semiconductor material is selectively dissolved or removed from a surface through a combination of light irradiation and electrochemical reactions. Light absorption generates electron-hole pairs in the semiconductor, which then participate in redox reactions at the semiconductor-electrolyte interface. This technique is used in microfabrication and surface patterning.",
