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.

About Tungsten Telluride WTe2 Powder:
Tungsten telluride (WTe2) is a transitional metal chalcogenide with a layered structure. In its orthogonal cell, the tungsten chain presents a one-dimensional distribution along the A axis of the tellurium layer. It is a kind of non-magnetic semi-metallic material.
Tungsten telluride (WTe2) is an inorganic semimetallic compound. Tungsten ditelluride is found to have very large magnetoresistance: at a magnetic field of 0.5 Kelvin, 60 teslas, the resistance increases by 13 million %. The resistance is proportional to the square of the magnetic field, showing unsaturation. This may be because the material is the first example of a compensating semi-metal where the number of movable holes is equal to the number of electrons tungsten ditelluride has a layered structure similar to many other transition metal halogen compounds, but its layered structure is distorted, and many of them share a honeycombed lattice that is difficult to identify in WTe2. Instead, tungsten atoms form zigzag chains that are thought to behave as one-dimensional conductors. Unlike electrons in other two-dimensional semiconductors, electrons in WTe2 can easily move between layers
The magnetoresistance effect in WTe2 decreases under pressure. When the pressure exceeds 10.5 GPa, the magnetoresistance disappears and the material becomes a superconductor. At 13.0 GPa, the superconducting transition occurs below 6.5 K.
Two – and three-layer thick WTe2 have also been observed to be polar metals, and the theory of electrical polarization with metallic behavior and conversion suggests that polarization is caused by vertical charge transfer between layers, which in turn is caused by interlayer sliding.
