  "id": "MLC-T-CHM-005250",
  "term": "Heterojunction",
  "field": "Chemistry",
  "definition": "A boundary formed between two dissimilar semiconductor materials, which have different band gaps. This interface creates a discontinuity in the electronic band structure, leading to unique electrical and optical properties. Heterojunctions are fundamental components in many electronic and optoelectronic devices, including solar cells and light-emitting diodes.",
