Capacitors could pave the way for flexible and superstrong electronic devices. Wonder material graphene was first isolated in 2004 at The University of Manchester by Professor Andre Geim and Professor Kostya Novoselov. Their work earned them the 2010 Nobel prize for Physics. Graphene is the world's thinnest, strongest and most conductive material, and has the potential to revolutionise a huge number of diverse applications; from smartphones and ultrafast broadband to drug delivery and computer chips. Combining graphene with other materials, such as the ideal insulator boron nitride, has been a particular area of success for the Manchester researchers – creating heterostructures which have unique properties. Capacitors made this way could prove cheaper and easier to make than traditional transistors. The team used quantum capacitance spectroscopy to investigate the exceptional properties of graphene, as this measurements shows better accuracy.
