Tin Telluride SnTe Powder Cas 12040-02-7

About Tin telluride SnTe powder:
Tin Telluride, IV-VI compound semiconductor material, is compounded from IVA element Sn and VIA element TE. The molecular formula is SNTE. The banned bandwidth is 0.60 eV, which is a direct transmitting type.

Tin Telluride is a semiconductor compound. Sodium chloride structure, ionic crystals, have a certain covalent bond component. Density 6.48g / cm3, melting 780 degrees Celsius. It is prepared by a straight pull method and an epitaxial method for making an infrared detector.

Tin Telluride is usually alloyed to make the lead tiny lisuride, which is used as infrared detector material. Tin Telluride typically forms a p-type semiconductor (external semiconductor) due to tin air space and is a low-temperature superconductor.

Tin Telluride exists in three crystal stages. At low temperatures, the concentration of the aperture carrier is less than 1.5 × 10 20 cm-3, which is also referred to as the α-SNET in the diamond phase. At room temperature and atmospheric pressure, tin TELLURIDE is present in the NaCl samples, called β-SNE. Although the β-SNTE is converted to γ-SNTE, γ-SNTE, orthogonal phase, and spatial group PNMA. The phase change is characterized by an increase of 11% and the resistance of the γ-SNET increases by 360%. Teti is a thermoelectric material. Theoretical research means that n-type performance may be particularly good. Feel free to send an inquiry to get the latest price if you would like to buy Tin telluride SnTe powder in bulk.

How is Molybdenum Telluride MoTe2 Powder Produced?
Molybdenum can form a series of homogeneous compounds with sulfur, selenium and tellurium. Molybdenum disulfide (MoS2), molybdenum selenide (MoS2) and molybdenum ditelluride (MoTe2) are heterogeneous iso phase compounds. These compounds are usually formed by combining the corresponding elements directly at high temperatures in a sealed vacuum tube.
MoTe2(Motex x=1.88 ~ 2) and Mo3Te4 can be formed by the reaction of MoTe2 and Mo3Te4 within 15 minutes at 430℃.
Reactive: Mo+2Te → MoTe2

Applications of Molybdenum Telluride MoTe2 Powder:
Potential uses of MoTe2 are lubricants, electronics, optoelectronics or photocell materials.

Make transistors with MoTe2.MoTe2 has the potential to manufacture low-power electronic products. Field-effect transistors (FETs) are made up of two, three, and thicker nanolayers. A bipolar field-effect transistor has been built, as well as a field-effect transistor that can operate in either N or P mode, with two top electrodes.

Because MoTe2 has two phases, it is possible to construct a device in the form of a 2H semiconductor and 1T’ metal.

The MOSFET can consist of a thin layer of MoTe2 covered by a gate consisting of an ionic liquid or a liquid electrolyte such as potassium perchlorate dissolved in polyethylene glycol. When the gate voltage is below 2 volts, the device operates in electrostatic mode, and the current from drain to source is proportional to the gate voltage. Beyond 2 volts, the device enters an intermediate region where the current does not increase. A current of more than 3.5 volts leaks through the gate and electrolysis occurs when potassium atoms are inserted into the MoTe2 layer. Potassium intercalated molybdenum ditelluride is superconducting below 2.8 K.

As a lubricant, molybdenum ditelluride works well in a vacuum at temperatures up to 500 ° C with a coefficient of friction below 0.1. However, molybdenum disulfide has less friction, whereas molybdenum diselenide can function at higher temperatures.

Molybdenum ditelluride can form at the contact point, and if this is n-type, then small pieces of the molybdenum ditelluride nano-layer can be mixed or dispersed in the molten tin without reacting, which doubles the stiffness of the composite.

Molybdenum ditelluride has been examined for protein substrates by atomic force microscopy. It is superior because proteins stick harder than traditional materials such as mica.

Storage Condition of Molybdenum Telluride MoTe2 Powder :
The damp reunion will affect MoTe2 powder dispersion performance and using effects, therefore, molybdenum telluride MoTe2 powder should be sealed in vacuum packing and stored in cool and dry room, molybdenum telluride can not be exposure to air. In addition, the MoTe2 powder should be avoided under stress.

Packing & Shipping of Molybdenum Telluride MoTe2 Powder :
We have many different kinds of packing which depend on the molybdenum telluride MoTe2 powder quantity.
Molybdenum telluride MoTe2 powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.

Magnesium Telluride

magnesium telluride is a white substance that crystallizes when it is heated in a combination of tellurium vapour and hydrogen. It is a strong and lightweight material with numerous applications in the industrial and medical arenas.

MgTe is a crystal grown product that is generally available in most volumes and is not as difficult to get your hands on as it sounds. The most obvious application of MgTe is as an anti-fouling coating for marine vessels. In the spectroscopic realm, it is used for gamma and X-ray detection in medical imaging devices as well as in a variety of other detectors.

Theoretical studies have shown that MgTe has a handful of interesting properties including: an optically thin semiconductor with a p-type conductivity, a nanoscale magnetic material, and a nifty tungsten telluride semiconductor. The fabled magnetic properties can be attributed to the presence of a large number of magnetized ions in the nanocrystals.

Most intriguing of all is the fact that MgTe is capable of generating a microsecond-scale magnetic pulse. This is not the sort of signal that can be obtained with conventional metallic electrodes. It also exhibits a remarkable reversible conductivity, with an excellent long-term stability.

MgTe is a great acomplishment in the field of anti-fouling coatings and can be used for a variety of other applications. The most important limiting factor in these applications is the cost. The material has the potential to be a game changer for many of these industries.

The Magic Antimony Telluride

Holographic Imaging Technology – Application of Antimony Telluride Researchers had explored previously how to reduce holographic imaging so that it is compatible with private devices. The traditional computer-generated Holograms are too large for most electronic devices. The size limit is being overcome by ultra-thin new holograms. On silicon wafers, the researchers created antimony leturide thin film 25 nanometers thick. Because of the low surface refractive Index and high internal refractive, optical resonators are possible and can even be enhanced for 3D Holographic Imaging. Laser etching is used to create the image from the antimony-telluride film. The researchers were able to make a 3-mm-long square hologram using these methods. This is a significant step forward.

Antimony Telluride Application in Thermoelectricity Generation

Know body temperature charging. The Zebek effect is the magic ingredient in the magical method. This circuit, typically composed of antimony telluride and bismuth thermoelectric substances, produces a thermoelectric energy if both metals are at different temperatures. A free-moving electron may flow through the electromotive force driven by potential energie, creating current and then generating electricity. It is useful not only for charging large gadgets, but for many other uses. You cannot underestimate the potential benefits of charging pacemakers, nanobots or other electronic devices using this technology. Tungstenmolybdenummetals (aka. Tungstenmolybdenummetals is an advanced material. With over 12 years’ experience, Tungstenmolybdenummetals is an established global supplier of chemical material. We produce [( telluride-antimony] that is high in purity, small particles and very low in impurities. We can help you if the purity is lower.
