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.

MoTeis also semi-metallic, with bulk MoTeexhibiting superconductivity at a transition temperature of 0.10 K.

We supply low price molybdenum ditelluride in several different forms for a range of applications.

Key Product Data

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.

Properties of Molybdenum Ditelluride

After exfoliation of Molybdenum ditelluride crystal or powder, Molybdenum ditelluride typically has the following properties:

  • Hexagonal 2H-MoTe(space group:  P63/mmc)
  • 2H-MoTe2 (α-MoTe2) is a semiconductor with an indirect band gap of around 1.0 eV in bulk crystal or powder form
  • Orthorhombic (Td) MoTe2 is a type II Weyl semimetal
  • Bulk MoTeexhibiting 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.

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 MoTehas 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.
