What do you mean by chalcogenide?
A chalcogenide is a chemical compound consisting of at least one chalcogen anion and at least one more electropositive element. Many metal ores exist as chalcogenides. Photoconductive chalcogenide glasses are used in xerography. Some pigments and catalysts are also based on chalcogenides.
What is chalcogenide semiconductors?
Compared to silica, chalcogenides show active properties and are very nonlinear. Additionally, chalcogenides are photosensitive, which is an advantage for designing structures into fibers. Besides, they are glassy semiconductors, which bring with them attractive electrical properties.
What are chalcogenide semiconductors give its applications?
Chalcogenides materials mostly exhibit semiconductive properties, and as such are suitable candidates for solar cells, optoelectronics, sensors, and thermoelectrics. Te, discussed earlier, is a prototypical semiconductor material, used for instance in infrared applications, X-ray and gamma detectors.
What is chalcogenide glass used for?
Despite this, chalcogenide-glass fibers are enabling numerous applications that include laser power delivery, chemical sensing, and imaging, scanning near field microscopy/spectroscopy, IR sources/lasers, amplifiers and optical switches.
What is chalcogenide material?
Chalcogenide materials are chemical compounds consisting of at least one chalcogen ion, i.e. a chemical element in column VI of the periodic table also known as the oxygen family. More precisely the term chalcogenide refers to the sulphides, selenides, and tellurides.
What is halide glass?
The term “halide glass” refers to glasses in which the anions are from elements in Group VIIA of the periodic table, namely, F, Cl, Br and I, as opposed, for example, to “oxide glasses,” such as silicates, borates, phosphates, etc.
Is oxide a chalcogenide?
2.1 Metal chalcogenides and their properties Although all of the elements in the VIA group are called chalcogens, the term metal chalcogenide is more commonly reserved for sulfides, selenites, and tellurites instead of oxides and polonium compounds.
What is a chalcogenide semiconductor?
Chalcogenides are chemical compounds that contain in their structure an element of the group (16 or VI A) of the periodic table. The term chalcogenide is used mainly to refer to some compounds containing sulfides, selenides, and tellurides. The application of this type of semiconductor is extensive and varied, mainly focused on energy storage.
What are the different types of metal chalcogenides?
According to the elements involved, metal chalcogenides can be categorized into transition metal and main group metal chalcogenides (MMCs), which will be briefly reviewed to give an overview of these materials.
Can chalcogenides be used as electrodes in electrochemical cells?
A composite of metal chalcogenides with C-polymers is always an interesting approach to engineer properties for electronic applications [39–41]. For application as an electrode material in an electrochemical cell, along with transition metal dichalcogenide, metal oxychalcogenides have also been explored.
What are the chalcogenides suitable for PCM?
The chalcogenides suitable for PCM concentrate in two major material classes. The first one is the pseudo-binary alloy along GeTe-Sb2 Te 3 line which is known as Ge–Sb–Te alloy (GST). The other one is the doped Sb 2 Te alloy such as Ag 5 In 5 Sb 60 Te 30 (AIST) [10].
