Molybdenum Ditelluride Powder and Crystal
Low price, high purity 2D molybdenum ditelluride (MoTe2) powder and crystals
Molybdenum Ditelluride MoTe2 (α-MoTe2) is a semiconductor with an indirect band gap of around 1.0 eV in bulk crystal or powder form, and a direct band-gap of about 1.1 eV in monolayer films. MoTe2 has a characteristic layered structure direct band-gap that extends to near infrared (NIR) wavelengths. Combined with the advantages of wet chemical exfoliation, MoTe2 has great potential for electronics - especially in photovoltaic technologies.
Single or few-layer MoTe2 nanosheets can be created via liquid exfoliation under ambient conditions. Exfoliated nanosheets can be be fabricated into layered films and deposited onto a range of different substrates. MoTe2 nanosheets can be used in high-performance sodium-ion batteries, as a electrocatalyst in hydrogen evolution reactions (HER), and in photovoltaic solar cells.
MoTe2 is also semi-metallic, with bulk MoTe2 exhibiting superconductivity at a transition temperature of 0.10 K.

Applications of Molybdenum Ditelluride
Molybdenum ditelluride single crystal can be used to prepare monolayer and few-layer MoTe2 by mechanical or liquid exfoliation, and Molybdenum ditelluride powder is suitable for liquid chemical exfoliation to prepare MoTe2 nanosheets and nanoparticles down to few-layer films.
With a relatively small band gap (1.1 eV) compared to other group VI TMDCs, single or few-layer MoTe2 is a promising candidate in a range of applications, including ambipolar transistors. Due to its low band-gap, it is also of interest in optoelectronic technologies that span the visible to near-infrared range.

Structure of Molybdenum Ditelluride
Molybdenum Ditelluride MoTe2 (α-MoTe2) is a semiconductor with an indirect band gap of around 1.0 eV in bulk crystal or powder form, and a direct band-gap of about 1.1 eV in monolayer films. Like MoS2 and other 2D materials, MoTe2 has a layered structure. It is composed of hexagonal sheets of molybdenum atoms - these are located between two hexagonal planes of tellurium atoms. Individual sheets are held together by weak Van der Waals forces, and are stacked with 2H symmetry.
Applications of Molybdenum Ditelluride
Molybdenum ditelluride (MoTe2) single crystals can be used to prepare monolayer and few-layer MoTe2 by mechanical or liquid exfoliation.
Molybdenum ditelluride powder is suitable for liquid chemical exfoliation to prepare MoTe2 nanosheets and nanoparticles down to few-layer films. Bulk MoTe2 exhibits superconductivity with a transition temperature of 0.10 K however potassium intercalated molybdenum ditelluride becomes superconducting below 2.8 K.
Monolayer or few-layer 2D MoTe2 has a direct band-gap and finds applications in transistors, and photovoltaics. MoTe2 nanosheets prepared by chemical exfoliation have a band-gap at near-infrared (NIR) wavelengths. Thus, they are of direct interest in photo-detector devices.
MoTe2 nanosheets can be used in high-performance sodium-ion batteries, as a electrocatalyst in hydrogen evolution reactions (HER), and in photovoltaic solar cells.
