Background
Electronic materials play a central role in applications such as energy storage, and electronic and opto-electronic devices. Batteries and supercapacitors require electrodes with large electrochemical activity and large electrical conductivity. Opto-electronic devices require light sensitive materials in combination with electrically conducting materials. Solar cells and light emitting diodes (LEDs) require optically transparent and highly conducting electrodes. Electrodes that incorporate oxide materials and various forms of carbon, such as carbon nanotubes and activated carbon, are used for energy storage, where the oxide material provides capacitance and the carbon materials provide electrical conductance. Similarly, carbon nanotubes have been combined with materials that respond to light. A significant disadvantage of this approach is that the electrodes, when composed of single-wall nanotubes are prohibitively expensive, while multiwall nanotubes do not have the required performance. Graphene films fabricated using room-temperature deposition processes have much lower fabrication costs but lack in required performance, such as electrical conductivity or electrochemical capacity. There is a need for a nano-scale electrically conducting material that, in combination of other nano-scale materials, acts as an electrode for an energy-storage and optoelectronics device.
