Applications of Graphdiyne on Optoelectronic Devices.

Abstract

Graphdiyne (GD) is a novel two-dimensional carbon material composed of sp and sp2-hybridized carbon atoms. This kind of carbon allotrope has attracted more and more attention not only because of the distinctive porous structure but also because of its intriguing electronic properties such as high mobility and conductivity, good field emission properties, and tunable natural band gap. In this review, some representative applications of GD on a variety of optoelectronic devices are described. Starting from the methods of introducing GD into the devices, we analyze the interactions between GD and other device components, summarize the general mechanism of how GD improves performance of the devices, and provide a glimpse into the future of GD at the end.
