Abstract
This chapter describes the discovery of a wide NDR region in a graphite silicone composite (GSC) at low temperatures. Experimental and theoretical evidence is used to demonstrate that the NDR originates from a semi-metal to insulator transition of embedded bilayers in specifically orientated graphite nanoparticles. NDR has not been observed before in a GSCs and could be exploited to create flexible oscillators and amplifiers, realizing flexible active electronic devices.
