Graphene inspires search for atomic lego University of Manchester Universities - Electronics Research

July 30, 2013

The University of Manchester is highlighting a review written for Nature, discussing how layered materials can be split into isolated atomic planes and then reassembled back in an intelligently-chosen sequence. Inspired by the promise of graphene, the idea is to create new kinds of materials and structures that do not exist in nature.

The authors? None other than Nobel Laureate Sir Andre Geim, one of the discoverers of graphene, and Dr Irina Grigorieva,

The university writes:

The authors point out that in addition to graphene there are many other one atom or one molecule thick crystals. These include monolayers of boron nitride (otherwise known as ‘white graphene’) and molybdenum disulphide which are already well characterized and attracted significant attention from academia and industry. The search for more atomically thin crystals is growing rapidly.

The graphene-like materials promise a range of their own applications but, in isolation, they are unlikely to offer the same remarkable properties as graphene itself – the world’s thinnest, strongest and most conductive material.

The most exciting development suggested, proven and now reviewed by University of Manchester researchers was creating ‘atomic Lego’; stacking these atomically-thin materials in heterostructures and artificial materials so that the resulting properties can be controlled and manipulated. Such materials made with a single plane precision could not be made by any previously-known technique.

“I believe this new research field is going to be as big as graphene itself,” said Geim. “It is already clear that graphene combined with other atomically-thin materials shows properties better or different from its own.”

“Because of the amount of possibilities of combining these graphene-like materials together in heterostructures is practically unlimited, there must be new materials with unique properties no-one has even dreamed of as yet. We are spoiled for choice.”

Dr Grigorieva added: “With so many graphene-like crystals out there, we are limited only by our imagination how to combine them. That is a very exciting time to be a materials scientist and explore this terra incognito of materials that you can literally design and then make layer by layer yourself.”
