Deposition of YBCO Nanoparticles on Graphene Using Matrix-assisted Pulsed Laser Evaporation

Abstract

-Matrix-assisted pulsed laser evaporation (MAPLE) process has demonstrated to deposit polymers with a contaminationfree fashion. Here, MAPLE process is applied to deposit yttrium barium copper oxide (YBCO) superconductor particles on graphene sheets. The microstructures and elemental composition of YBCO nanoparticle deposited on graphene sheet by the MAPLE process were studied as a function of the irradiation time (t). The amount of YBCO nanoparticles deposited on graphene is increased with increasing t. The average particle size of the spherical YBCO nanoparticles deposited on graphene sheets is decreased from 70±25 nm to 50 ± 15 nm when t increases from 0.5 hr to 2.0 hr. This study demonstrates that MAPLE is a suitable process for depositing superconductor nanoparticles on graphene sheets.
