Synthesis of Graphene Nanostructures and Nanocomposites for Memristive Devices

Abstract

Graphene has had its share of fame and promise for fair part of our technological wonder and has kept churning out technological breakthroughs one after the other in past decade. The industry and academia are focused to discover and harness all the possible revelations this wonderful allotrope of carbon has on offer. Graphene and other members of 2D material family have been researched for wide range of properties such as photonic, electronic and mechanical properties. Resistive switching in materials has been studied in one way or the other since 1960s. However memristive devices have gained a lot of interest after experimental fabrication of the memristive device by Hewlett-Packard labs proving the mathematical proposition by Chua. This work is focused on synthesis of graphene nanostructures in form of nanoflakes and quantum dots, and the composites with polymers. The electrohydrodynamic atomization and other printed technologies were employed to fabricate resistive switching devices on PET and glass as substrate materials. The futuristic flexible printed memristors have also been explored and reported in this work. The technique employed to synthesize graphene quantum dots was used for synthesis of luminescent quantum dots of MoS2 as well. Thus providing a promising technique worth further exploration for synthesis of quantum dots of other 2D materials.
