Due to their excellent optoelectrical performance, processability, stability, and high conductivity, CNT-based transparent electrode films have been put forward as a candidate to replace indium tin oxide (ITO) currently used in touchscreens and displays.
CNTs are deposited in thin films, leading to a conducting layer, which can also be transparent. In relation to ITO they are more cost effective, have higher resistivity and greater flexibility. Main applications of CNT in electronics are:
Graphene has remarkable electronic properties, with an extraordinarily high charge carrier mobility and conductivity. It is an excellent conductor, and transports electrons tens of times faster than silicon. These properties make it an ideal candidate for next generation electronic applications.
Near-medium term electronics applications for graphene are in radio-frequency identification tags, low-resolution displays and backlights, sensors, electrical contacts, analog signal processing and electronics packaging. Initially applications will be in low-end electronics, depending on the manufacturing cost. High-end electronics applications are more cost sensitive.
The scalability, reproducibility and cost effectiveness of integrating graphene into practical devices is currently under development. Graphene's success in transparent conductive films (TCFs) is also dependent on the development of competing alternative materials. The demand for TCFs is increasing significantly as electronic devices such as touch screens, displays, solid-state lighting and photovoltaics become ubiquitous.
