But unlike graphene, molybdenum disulfide is a semiconductor. We've identified a wide range of what are termed 2D materials. These all form repeated chemical bonds in more or less a single plane.

This materials research establishes that it is possible to create metastable 2D pentagonal materials, considered difficult to make, thus enriching the 2D materials family, which so far is dominated by ...
