Creating perfect edges in 2-D-materials

Ultrathin materials such as graphene promise a revolution in nanoscience and technology. Researchers at Chalmers University of Technology, Sweden, have published a study in Nature Communications in which they present a method ...

Intelligent nanomaterials for photonics

Since the Nobel Prize in Physics was awarded for research on graphene in 2010, 2-D materials—nanosheets with atomic thickness—have been a hot topic in science. This significant interest is due to their outstanding properties, ...

A new all-2-D light-emitting field-effect transistor

Transition metal dichalcogenides (TMDs), a two-dimensional (2-D) semiconductor, are promising materials for next-generation optoelectronic devices. They can emit strong light due to the large binding energies of excitons, ...

Spectral classification of excitons

Ultrathin layers of tungsten diselenide have potential applications in opto-electronics and quantum technologies. LMU researchers have now explored how this material interacts with light in the presence of strong magnetic ...

Phasing out a microscope's tricks

An instrument error can lead to complete misidentification of certain crystals, reports a KAUST study that suggests researchers need to exercise caution when using electron microscopes to probe two-dimensional (2-D) semiconductors.

Peel-apart surfaces drive transistors to the ledge

Semiconductor manufacturers are paying more attention to two-dimensional materials, such as transition metal dichalcogenides (TMDs), following the discovery, at KAUST, of an epitaxial growth process of single-crystal TMDs ...
