Title : Modification in the electronic properties of CVD grown SLG by deposition of thin transparent conducting polymer
Abstract:
The development of flexible and stretchable electronic devices such as solar cells, touch screen displays, light emitting diodes, flexible batteries, and sensors are the essential requirement of modern era. The essential components of these devices are electrodes, which should be thin, lightweight, and highly transparent so that they can be stretched and flexed without compromising their electrical and optical assets. Recently, graphene has received considerable interest for the electrode material due to its remarkable properties, including atomically thin, high mechanical strength, thermally stable, and highly transparent two-dimensional sheets. However, graphene shows low carrier concentration. The modulation of charge carrier and doping type of graphene is a potential step for the realization of multifunctional use in current electronic devices. Here, we present tuning in electronic features of the chemical vapour deposition (CVD) grown mono layer graphene by deposition of transparent conducting polymer. The effect of deposition on graphene samples were examined by Raman spectroscopy, electrical transport measurement, atomic force microscopy, and Kelvin probe force microscopy. Our finding will be useful for understanding the device physics as well as improvement of photovoltaic devices based on PEDOT:PSS coated graphene.
