Indium tin oxide and indium phosphide harm the pulmonary and immune systems, predominantly through ionic indium, [91] though hydrated indium oxide is more than forty times as toxic when injected, measured by the quantity of indium introduced. [21] People can be exposed to indium in the workplace by inhalation, ingestion, skin contact, and eye ...
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Field effect transistors were fabricated from those. [11] Indium oxide nanowires can serve as sensitive and specific redox protein sensors. [12] The sol–gel method is another way to prepare nanowires. [citation needed] Indium oxide can serve as a semiconductor material, forming heterojunctions with p-InP, n-GaAs, n-Si, and other
The periodic table and law are now a central and indispensable part of modern chemistry. The periodic table continues to evolve with the progress of science. In nature, only elements up to atomic number 94 exist; [a] to go further, it was necessary to synthesize new elements in the laboratory.
The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table.
Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.
HEMT devices using InGaAs channels are one of the fastest types of transistor [30] [citation needed] In 2012 MIT researchers announced the smallest transistor ever built from a material other than silicon. [31] The Metal oxide semiconductor field-effect transistor is 22 nanometers long. This is a promising accomplishment, but more work is ...
An oxide thin-film transistor (oxide TFT) or metal oxide thin film transistor is a type of thin film transistor where the semiconductor is a metal oxide compound. An oxide TFT is distinct from a metal oxide field effect transistor where the word "oxide" refers to the insulating gate dielectric (normally silicon dioxide). In an oxide TFT, the ...
