Negative refraction in molybdenum disulfide

Optics Express, 2015
Recently, negative refractions have been demonstrated in uniaxial crystals with no necessary of negative permittivity and permeability. However, the small anisotropy parameterγin the uniaxial crystals limits the negative refraction occurrence only in a small range of the incident light angle, retarding its practical applications.

An Alternative Route to Molybdenum Disulfide Nanotubes

Journal of the American Chemical Society, 2000
Molybdenum disulfide ((MoS2)n) nanotubes are generated when polycrystalline MoS2 powder, covered by Mo foil, is heated to ca. 1300 °C in the presence of H2S. Electron diffraction reveals the presence of zigzag arrangements within the tube walls.

Defect Engineering of Two‐Dimensional Molybdenum Disulfide

Chemistry – A European Journal, 2020
AbstractTwo‐dimensional (2D) molybdenum disulfide (MoS2) holds great promise in electronic and optoelectronic applications owing to its unique structure and intriguing properties. The intrinsic defects such as sulfur vacancies (SVs) of MoS2 nanosheets are found to be detrimental to the device efficiency.
