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.
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.
insulator, conductor and semiconductor
Lithography is a technique used to make patterns on semiconductor materials.
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.
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.

Water can react with the semiconductor materials, such as silicon, and potentially corrode or degrade them. Oil is non-reactive with semiconductor materials, making it a better choice for dipping semiconductor specimens for protection during storage and handling.
we dont get an appreciable current in dis case...dats why we dope n get curret for practical use...

The most common items a semiconductor is used for is electrical components. These include computer processing units, graphic processing units, and transistors.
Intrinsic silicon is pure silicon with no intentional impurities added. It has a balanced number of positive and negative charge carriers, making it an electrical insulator at room temperature. Intrinsic silicon is the base material used in semiconductor device fabrication.
Lithography is a technique used to make patterns on semiconductor materials.
The most common metalloid used as a semiconductor is silicon. It is widely used in electronic devices and integrated circuits due to its abundant availability, stability, and controllable electrical properties.
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.
Arsenic is not a semiconductor by itself, but it is commonly used as a dopant in semiconductor materials like silicon to alter their electrical properties. Arsenic increases the number of available charge carriers in the material, which can make it conduct electricity more effectively.
Argon can be found in fluorescent light bulbs, lasers, and some welding applications. It is also used in the production of semiconductor materials and as a gas for protecting materials from oxidation during manufacturing processes.
