New 2D crystal might surpass graphene's electrical features

Researchers at the Ulsan National Institute of Science and Technology (UNIST) in Korea managed to synthesize a new multifunctional 2D ordered crystal structure, designated as C2N-h2D crystal, that they claim exhibits more enhanced electrical features than those of graphene. 

The thin-layered micrometre-sized 2D crystal was the result of a reaction between ​hexaaminobenzene trihydrochloride and ​hexaketocyclohexane octahydrate and it exhibits a strong semiconducting nature, as it has a large Ion/Ioff ratio that equals a fast switching speed for semiconducting devices. The Ion/Ioff ratio of the C2N-h2D crystal was confirmed to be 100 times more efficient than current silicone semiconductors in production.

According to the scientists, the unique structure and the simple and efficient synthesis of the C2N-h2D crystals may enable its use in various applications - including ones where graphene has proven to be unsuitable.
