Atomically MoS2 and WS2 Thin Semiconductors for Nanophotonics

atomically thin semiconductor image

Atomically thin layers of semiconductors, such as molybdenum disulfide (MoS2) and tungsten disulfide (WS2), are promising materials for nanoscale photonic devices. These nearly two-dimensional semiconductor support so-called excitons or bound electron-hole pairs, which can be aligned vertically along the thin planes of the material.

2D Molybdenum Diselenide and Its Hybrids for Hydrogen Generation Applications

2H to 1T phase transformation of 2D MoSe2 image

Hydrogen (H2) is a green and economical alternative to conventional fossil fuels due to its zero carbon emission. 2D molybdenum diselenide (MoSe2) hosts significant applications in hydrogen generation due to its low hydrogen adsorption Gibbs free energy and good electrical conductivity. The development of efficient hydrogen evolution reaction (HER) catalysts is of great interest for economical green hydrogen production.

Application of Tungsten Grinders in Welding

Tungsten grinders in welding image

Tungsten grinders usually hold powerful motors and work by using grinding wheels to remove material from metal workpieces. This equipment could be used for grinding, slicing, polishing as well as welding. Since tungsten rod grinders are more robust than other types of grinders, they are also commonly used in the automotive sector.

Hydrogen-Impurity Induced Magnetism in Molybdenum Ditelluride

Comparison of soft X-ray ARPES spectra image

A recent study demonstrates hydrogen-impurity induced magnetism in molybdenum ditelluride (MoTe2). Layered transition-metal dichalcogenides (TMDs) are a promising class of materials with optoelectronic, superconducting, catalytic, and topological properties. In TMDs, the polymorphic MoTe2 exhibits various electronic and magnetic properties. Its metallic 1T' phase turns into a Td phase at ≈250 K. The latter is a topological Weyl semimetal with unconventional superconductivity at low temperatures.
