Graphene Electronics

 Graphene Electronics

Graphene for Use in Flexible Electronics
Graphene has been used as the transparent conductive electrode in fabricating organic field effect transistor (OFET) and light emitting diode (LED) devices for use in flexible electronic displays. Graphene is suitable for flexible electronics because of its outstanding elastic and optoelectronic properties.

Graphene for Use in Electronics Transistors
By inducing a bandgap or introducing negative resistance, graphene can be used as the semiconductor in field effect transistors (FETs). Transistor based memory for computers that use silicon chip technology are close to the theoretical limits in size (5-10 nm). Carbon nanomaterials such as carbon nanotubes and graphene, however, have been used to make single transistors 1 nm in size.

Graphene for Use in Electronics Displays
New research shows that graphene can be utilized to create thinner, more flexible, and more durable light emitting devices for use in next-generation mobile phones, tablets and televisions. Graphene’s transparency, mechanical strength, and electrically conductive properties make it ideally suited to satisfy the electrical and optical requirements for next-generation display applications.

Graphene for Use in Electronics Sensors
Graphene-based field effect transistors (FETs) have been used in sensors for chemicals and biomolecules. Graphene oxide has been used as a fluorescence quenching material in biosensors that utilize the fluorescence resonance energy transfer (FRET) effect.
