Micro-supercapacitors on silicon with superior power densities based on solid source MXenes growth
Abstract
MXenes are the latest new family of 2D materials, including a family of 2D transition metal carbides, reported to possess conductivities and electrochemical properties even more favourable than those of graphene for their use as electrodes for supercapacitors.The bulk of the scientific research on MXenes so far has been conducted using solution –based synthesis and extracting flakes, while there are only a few examples of bottom –up CVD growth of MXenes in the literature. The research here proposed will address this gap, and its foundation lies in my group’s pioneering approach to the solid –state source growth of graphene on silicon carbide on silicon, enabled by a specifically -tailored alloy of metal catalysts. While similar concepts will be explored, challenges will arise by the need of a controlled carbidization step and in general the additional structural complexity of ordered MXenes as compared to graphene.This project, if successful, would enable for the first time the direct and site -selective growth of MXenes on silicon wafers to be seamlessly implemented as interdigitated electrodes for micro-supercapacitors with exceptional areal energy density.
