Chapter 9 - Graphene and optoelectronics

Abstract

Graphene has an incredible wealth of optical and electrical properties. In addition to durability, robustness, and environmental resilience, graphene has high mobility and optical transparency. To date, theoretical physics and electronic systems have been a big priority. However, we assume its true potential lies within photonics and optoelectronics, even in the absence of a complete image of its characteristics, the combination of its unique optical and electronic properties can be thoroughly utilized. In this chapter, we present a comprehensive review of recent developments in graphene-based devices. Light emissions from graphene-based devices have been evaluated with different aspects, such as thermal emission, electroluminescence, and plasmons-assisted emission. Theoretical investigations and experimental demonstrations in the development of graphene-based devices have also been reviewed and discussed. Finally, this review comprehensively discusses current technological issues and challenges related to the potential applications of emerging graphene-based devices such as photodiodes, solar cells, and light-emitting diodes.
