semiconductor

1. A substance as germanium or silicon whose electrical conductivity is intermediate between that of a metal and an insulator;
   Its conductivity increases with temperature and in the presence of impurities (synset 114845418)
   is a type of: conductor - a substance that readily conducts e.g. electricity and heat
   subtypes:

   • atomic number 32, ge, germanium - a brittle grey crystalline element that is a semiconducting metalloid (resembling silicon) used in transistors; occurs in germanite and argyrodite
   • atomic number 14, si, silicon - a tetravalent nonmetallic element; next to oxygen it is the most abundant element in the earth's crust; occurs in clay and feldspar and granite and quartz and sand; used as a semiconductor in transistors
   substance meronym: semiconductor, semiconductor device, semiconductor unit - a conductor made with semiconducting material
   same as: semiconducting material
2. A conductor made with semiconducting material (synset 104178892)
   is a type of: conductor - a device designed to transmit electricity, heat, etc.
   subtypes:

   • chip, micro chip, microchip, microprocessor chip, silicon chip - electronic equipment consisting of a small crystal of a silicon semiconductor fabricated to carry out a number of electronic functions in an integrated circuit
   • crystal rectifier, diode, junction rectifier, semiconductor diode - a semiconductor that consists of a p-n junction
   • n-type semiconductor - a semiconductor in which electrical conduction is due chiefly to the movement of electrons
   • p-type semiconductor - a semiconductor in which electrical conduction is due chiefly to the movement of positive holes
   • thermal resistor, thermistor - 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
   • electronic transistor, junction transistor, transistor - a semiconductor device capable of amplification
   substance holonym: semiconducting material, semiconductor - a substance as germanium or silicon whose electrical conductivity is intermediate between that of a metal and an insulator; its conductivity increases with temperature and in the presence of impurities
   same as: semiconductor device, semiconductor unit
