Graphene in Electronics
Driven by demand from markets where advanced materials are required, graphene promises to outstrip all current nanomaterials, especially in electronics applications. Revenues for smartphones and tablets now outstrip the entire consumer electronics (CE) market, with revenues of over $325 billion in 2013. Graphene will drive the next generation of transparent conductive films for displays.
Graphene in Electronics Properties
The exceptional electron and thermal transport, mechanincal properties, chemical stability of graphene and combinations thereof make it a potentially disruptive technology for electronics applications. Application areas at different stages of commercial development include:
- Transparent Conductors
- Optical Switches
- Transistors and Integrated Circuit
- Memory Devices
- Spintronics.
Graphene in Electronics Products
China is expecting to bring graphene products to the market in 2014 in consumer electronics. Companies such as IBM, LG Electronics and Samsung are pursuing applications for graphene in electronics, photonics and optics.Most large companies have a “wait and see” strategy as the commercial value has yet to be quantified and most research is at the fundamental stage.
Graphene in Electronics Competition
Graphene as a new material still faces many challenges ranging from synthesis and characterization to the final device fabrication. Barriers to widespread industry uptake mirror carbon nanotubes in many respects: functionalization and dispersion; mass manufacturing at an acceptable cost (a major issue); need for application partnerships; and health and safety issues.
Competition from silicon in semiconductors and sensors as well as carbon fiber (composites) is significant. Other competing technologies include sliver nanowires and carbon nanotubes as well as other 2D materials such as boron nitride, molybdenum disulfide, tungsten tungsten disulfide and germanane. Due to graphene’s comparable or better properties and lower production cost, carbon nanotubes will be replaced in applications which do not significantly benefit from nanotubes’ 1-D nature.
