Key Points

  • To investigate how trap-mediated photocarrier dynamics influence the performance of hybrid organic-inorganic heterojunction phototransistors.
  • Characterization of type-II heterojunction phototransistors
  • Analysis of photoinduced electron transfer mechanisms
  • Assessment of photocarrier trapping effects
  • Enhanced photoresponse observed in devices with trap-mediated dynamics
  • Clear evidence of electron transfer from organic layer to channel
  • Induced holes remained trapped, impacting overall device behavior

Abstract

Trap-mediated photocarrier dynamics fundamentally govern the photoresponse of hybrid organic–inorganic heterojunction phototransistors. In phototransistors with type-II heterojunctions, photoinduced electron transfer from the organic layer to the channel leaves holes trapped...
