Classical physics states that a crystal consists of perfectly ordered particles from a continuous symmetrical atomic structure. The Mermin-Wagner theorem from 1966 broke with this view: it states that in one-dimensional and two-dimensional atomic structures (for example in an atomic chain or membrane) there cannot be perfect ordering of particles over long ranges.
Researchers have developed a technique for converting positively charged (p-type) reduced graphene oxide (rGO) into negatively charged (n-type) rGO, creating a layered material that can be used to develop rGO-based transistors for use in electronic devices.
An international team of researchers has developed a method for depositing single magnetisable atoms onto a surface. This is especially interesting for the development of new miniature data storage devices.
Block polymers, which are two or more polymer chains with different properties linked together, show great promise for many of these applications, and a research group has made significant strides in their development over the past several years.
A novel supramolecular strategy introduces tunable 1D periodic potentials upon self-assembly of ad hoc organic building blocks on graphene, opening the way to the realization of hybrid organic- inorganic multilayer materials with unique electronic and optical properties.
Researchers have disclosed a new method to add chemical groups on single layer and bilayer graphene lying on silica/silicon. This study also suggests how decorated graphene serves as a platform to produce 2D materials with new characteristics.
