#semiconductor_device__semiconductordevice__semiconductor_unit__semiconductorunit__semiconductor  a conductor made with semiconducting material
  supertype:  conductor  a device designed to transmit electricity, heat, etc.
  member:  semiconductor
  subtype:  semiconductor_diode__semiconductordiode__diode__junction_rectifier__crystal_rectifier__crystalrectifier  a semiconductor that consists of a p-n junction
     subtype:  light-emitting_diode__LED  diode such that light emitted at a p-n junction is proportional to the bias current; color depends on the material used
  subtype:  n-type_semiconductor  a semiconductor in which electrical conduction is due chiefly to the movement of electrons
  subtype:  p-type_semiconductor  a semiconductor in which electrical conduction is due chiefly to the movement of positive holes
  subtype:  thermistor__thermal_resistor__thermalresistor  a semiconductor device made of materials whose resistance varies as a function of temperature; can be used to compensate for temperature variation in other components of a circuit
  subtype:  electronic_transistor__transistor__junction_transistor  a semiconductor device capable of amplification
     subtype:  p-n-p_transistor__pnptransistor  a junction transistor having an n-type semiconductor between a p-type semiconductor that serves as an emitter and a p-type semiconductor that serves as a collector
