Surface recombination

  "id": "MLC-T-CHM-011660",
  "term": "Surface recombination",
  "field": "Chemistry",
  "definition": "The process where photogenerated electron-hole pairs in a semiconductor material recombine at the surface or interface, rather than migrating to participate in a chemical reaction. This phenomenon reduces the efficiency of photocatalytic and photovoltaic devices. The rate of surface recombination is influenced by surface defects and the presence of surface states.",
  "subject": "Physical and Biophysical Chemistry",
