Graphene And Flexible Electronics
Graphene is a two dimensional form of carbon which is one atom thick layer of graphite. It is around 100 times stronger than steel and has a conductivity which is much better than copper. High charge carrier mobility – 10,000 cm square/Vs. It is the strongest and thinnest material known to exist. Due to its electronic properties, it absorbs 2.3% of light that passes through it. Signal flowing through the devices made of graphene can flow with speeds greater than the speed of light. High thermal conductivity, chips with better dissipating heat can be made. Antennas, transistors, batteries and touch screens become more efficient and flexible when created by using Graphene. It has a modulation depth of 64% with GHz bandwidth whereas silicon has a modulation depth of 46%.
