Scientists identify hundreds of atomically-thin materials

Computer scanning within existing databases revealed hundreds of new materials, not previously defined, but only at atomic size.

Graphite may seem like a miracle of the modern world but it is actually found in graphite for centuries on earth. A graph is a layer of interatomic carbon atoms. Graphite is the aggregate of these layers on top of each other.

Since then, other chemistries have been identified that only form strata at a few atomic masses. These chemicals have different properties. Those with semiconductor characteristics have been brought together with grain for use in the production of electronic devices. It could be quite useful to get more of these types of chemistries to expand the device range that can be made based on the advantages that materials with thinness at atomic level have brought with them.

A team of researchers from Lithuania and Switzerland seems to have done it. The graphite-like material that the team finds consists of a stack of atomically thin layers hidden within each other.

This work is largely based on what other scientists share as open sources. This information is made up of a large database of high-order chemical structures. For example, the Inorganic Crystal Structure Database contains about 100,000 unique crystal structures. All these structures provide details of how atoms of a material are arranged in three-dimensional space.

A different research from the typical database research

Researchers who have studied have developed a computer code that can search between things such as graphite. Graphite has strong chemical bonds between the carbon atoms in each layer.
For this reason, the researcher’s new software has searched for something similar: strong chemical bonds on a plane, and this planar rather weak, non-chemical interaction on a steep surface.

In many cases these materials are structurally similar in terms of the positions of the atoms and the chemical bonds between them. For example, molybdenum disulphate, together with an atomically fine sample of materials, have identified 13 additional chemicals that make up the researchers conducting the study.

Electron View

n order to show what type of material we can add to the list of available chemicals, researchers have calculated what electrons in 258 less complex chemistries might be doing. Although the potential between baseline and transmission states varies from zero to 1.5 electronVolts, a majority (166) of them are found to be semiconductors. 92 materials were found to be metallic. Another group of 56 units exhibited unusual magnetic properties, and some were found to exhibit behaviors related to the rotation of electrons, such as half-electrons.
