Graphene doping for electrode application

Abstract

Graphene has introduced as a single layer of honeycomb carbon atoms, and has been attracted due to its outstanding physical, optical, and electronic properties. There are various methods to synthesize the graphene, and chemical vapor deposition can offer an excellent approach to prepare large-scale graphene for flexible transparent conducting electrodes with low resistance and high transmittance. These unique properties enable the graphene to be utilized as efficient transparent electrodes for optoelectronic devices, commercially. However, there are some issues that need to be solved. For example, the energy level difference between graphene and the active layer in an optoelectronic device can decrease the efficiency. Therefore, the tuning and modulation of graphene should be considered to enhance device performance. In this chapter, we aim to investigate the optical and electrical properties of the graphene-based transparent electrodes and the effect of doping graphene on properties for optoelectronic applications. © 2020 Elsevier Ltd.
