A semiconductor is a substance that has specific electrical properties that enable it to serve as a foundation for computers and other electronic devices. It is typically a solid chemical element or compound that conducts electricity under certain conditions but not others. This makes it an ideal m...
An element is an atomic species with several sub-atomic particles like protons, neutrons, and electrons. Hence, an element cannot be broken further into small pieces. Thus, two or more elements combine to form compounds.Answer...
a) Cadmium b) Lead c) Arsenic d) Mercury What is the most important ore of aluminium metal? Explain the difference between iron in the body and the element iron. Is there a metal-metal bond in (Cu(OAc)_2(H_2O))_2? Explain. What are some applications of metals...
Semiconductor materials include – Silicon,antimony, arsenic, boron, carbon, germanium, gallium arsenide, selenium, silicon carbide, sulfur, tellurium, oxides of most metals. What is Superconductor? Superconductor is an element, inter-metallic alloy, or a compound that conducts electricity without resist...
As a result, their conductivity is relatively low and highly dependent on temperature. Extrinsic semiconductors, on the other hand, are created by introducing impurities into the intrinsic material through a process called doping. Doping involves adding a small amount of another eleme...
The metallic form of the element is brittle and it gets tarnished when oxidized to arsenic trioxide. Its non-metallic form is less reactive but easily dissolves when heated with strong oxidizing acids and alkalis. Arsenic is a steel-gray, brittle solid with low thermal and electrical conductivity...
Classify the following elements as metal, nonmetal, or metalloid. A. chlorine B. zinc C. arsenic Is silicon classified as a metal, a metalloid, or a nonmetal? Explain. Which elements on the periodic table are diatomic? What is the 10th element on the periodic table?
Intrinsic semiconductors are pure materials, namely silicon and germanium, that have a natural ability to conduct electricity when in contact with a heating element. As is, however, these undoped materials do not conduct electrical currents very well. ...
the silicon becomes slightly charged and capable of conducting electricity. When the doping element has an extra valence electron it becomes a negatively chargedn-typeconductor. Common n-type doping elements are phosphorus, arsenic and bismuth. When the doping element is missing an electron from its...
This enables a current to flow if a potential is applied across the material. As this type of material has a surplus of electrons in the lattice it is known as an N-type semiconductor. Typical impurities that are often used to create N-type semiconductors are phosphorous and arsenic. It ...
