- aluminum phosphide
- gallium arsenide
- indium antimonide
- boron phosphide
- boron arsenide

- indium nitride
- indium phosphide
- indium arsenide
- etc.
There are also other types of semiconductors, like copper oxide, selenium, cadmium sulfide, and lead sulfide. However the properties of these semiconductors are harder to control than those listed above, thus they have few uses in modern electronics.
Carbon in the form of nanotubes or high purity diamond thin films also offers promise as a semiconductor. It should work at much higher temperatures than other semiconductors can, but fabrication problems remain to be solved before it can be used in practical devices.

What you understand by the term intrinsic semiconductor and how an intrinsic semiconductor is turned into either a p type or an n type material?
An intransic material is a material that have been used in doping process.There are two type of intrinsic material n type and p type.
What are the three categories of materials used in electronics?
insulator, conductor and semiconductor
What is lithography in IC fabrication?
Lithography is a technique used to make patterns on semiconductor materials.
Why intrinsic conductor not used in electronic devices?
Intrinsic semiconductors have small conductivity at the room temperature. and also if we raise the temperature to increase their conductivity then they will start acting merely like a conductor. and there will not be any control over the directions or the magnitude of the current flowing through it. so by mixing the suitable impurity(dopant) we obtain the extrinsic semiconductor. so that the conductivity as well as the control over the current can be increased. Although intrinsic semiconductor are also somwhere used in electronics where i high resistance layers or a separation layers b/t two systems is needed. like in PIN diode.
Why is semiconductor used for current instead of normal conductor materials?
The kind of material used in a device depends on its requirements and functions. Semiconductors are used where we need moderate conductivity, conductors are used where we need very high conductivity. Junction diodes(a semiconductor device) allows electricity to pass in one direction and can be used as rectifier. Conductors can't do this. Transistors and LED are other applications of semiconductor. Note that generally devices are made of both conductors and semiconductors.

What is the most common metalloid used as a semiconductor?
Silicon
What is the narrow-band semiconductor?
Narrow-band semiconductor refers to the semiconductor materials with band gap that is relatively smaller than silicon. This is commonly used as thermo-electric or infrared detectors.
What common items could a semiconductor be used for?
The most common items a semiconductor is used for is electrical components. These include computer processing units, graphic processing units, and transistors.
What is lithography in IC fabrication?
Lithography is a technique used to make patterns on semiconductor materials.
What are the semiconductor materials used in computers?
A material that is neither a good conductor of electricity (like copper) nor a good insulator (like rubber). The most common semiconductor materials are silicon and germanium. These materials are then doped to create an excess or lack of electrons. Computer chips, both for CPU and RAM (or memory), are composed of semiconductor materials. Semiconductors make it possible to miniaturize electronic components, such as transistors. Not only does miniaturization mean that the components take up less space, it also means that they are faster and require less energy.

What are the advantage of semiconductor over conductor?
semiconductors are the conducors they are partially conduct electricity. And we can increase therir conductivity by using various method . They are Intrinsic method and extrinsic method . Intrinsic method is heating the semiconducter . Extrinsic method is doping. By using this method the conductivity of semiconductors is rapidly increases. Then we use semiconductors are prefferd to conductors
What is intrinsic scmicondoctor?
A completely pure semiconductor crystal is called intrinsic, to underline that no substance is inserted in the crystal as impurity. An intrinsic semiconductor has a very low conductivity (it is almost an insulator, even if a current can flow if it undergoes a great voltage difference. Selected intrinsic semiconductors like Indium Phosphate (InP) or Gallium Arsenide (GaAs) are instead very effective in creating photo-stimulated electrical current (that is electrical current due to absorption of incident light) at a specific frequency called resonance frequency of the semiconductor. Other semiconductors (like Silicon, Si) lack this capability. This difference is related to the quantum mechanical behaviour of electrons in the different crystals. A semiconductor crystal where selected substances called dopants (like phosphorous or arsenic) are inserted in the crystal to give it particular properties is called doped semiconductor. Doping is more frequently used to create free charges in the semiconductor and increase conductivity. Depending on the sign of the virtual particle generated by doping in the crystal the doped semiconductor is called p doped (positive carrier generated) or n doped (negative carrier generated).
