Graphene has unique electric, optical and mechanical properties. The high electronic mobility and compact size can improve the performance of electronics. The high thermal conductivity can conduct heat easier so the heat accumulation problem can be solved in smaller electronics. Flexible and light graphene-based electronics possibly can make the products more wearable, portable, durable and affordable. With the progress in fabrication methods, graphene-based electronics can be fabricated and integrated more easily.

A modified preliminary model shows how graphene-related parameters can affect quantum tunneling in graphene-based electronic devices. Conventional quantum tunneling can be affected by parameters such as material work function, applied electric field, effective mass of material. In the modified model, the graphene-related parameters such as the number of graphene layer can affect the quantum tunneling in nano electronic devices.  Quantum tunneling in carbon nanotube-based electronic devices will be also discussed and compared. Future work and possible applications will be proposed.
