Abstract

Abstract : In this paper, results for the adhesion energy of graphene and MoS2 to silicon based and metal substrates using the intercalation of nanoparticles method are presented. In this method, nanoparticles are dispersed onto the substrates before transferring the 2D material onto the substrate. This causes a blister to form, the width and height of which can be measured by AFM. Using a simple model then allows for the adhesion energy to be found. The substrates tested are SiO2, Si­3 N4, gold, and platinum. Gold is found to have the highest adhesion energy per area of 7687.10 and 1207.26 mJ m −2 for graphene and MoS2 respectively. Abstract : Intercalated nanoparticles are used to determine the adhesion energies of 2‐D layers to different substrates such as graphene and MoS2 to Au, Pt, SiNx, and SiO2 substrates. The figure illustrates an intercalated nanoparticle between the substrate and graphene. Through this method, Au shows the strongest adhesion energy of 7687.10 and 1207.26 mJ m−2 for graphene and MoS2, respectively.
