Definitions of semiconductor

n 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

semiconducting material
Ge, atomic number 32, germanium
a brittle grey crystalline element that is a semiconducting metalloid (resembling silicon) used in transistors; occurs in germanite and argyrodite
Si, atomic number 14, 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
Type of:
a substance that readily conducts e.g. electricity and heat

n a conductor made with semiconducting material

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
a microchip that uses tiny strands of DNA to latch onto and quickly recognize thousands of genes at a time; intended for use in a biological environment
FET, field-effect transistor
a transistor in which most current flows in a channel whose effective resistance can be controlled by a transverse electric field
DNA chip, gene chip
a microchip that holds DNA probes that form half of the DNA double helix and can recognize DNA from samples being tested
LED, light-emitting diode
diode such that light emitted at a p-n junction is proportional to the bias current; color depends on the material used
memory chip
a RAM microchip that can be plugged into a computer to provide additional memory
integrated circuit semiconductor chip that performs the bulk of the processing and controls the parts of a system
p-n-p transistor
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
Type of:
a device designed to transmit electricity, heat, etc.
