Laser-Induced Forward Transfer of Graphene Nanoribbons

The transfer of synthesized graphene nanoribbons with the initial characteristics obtained on the growth surface is an urgent and complex problem. Laser methods proved themselves well as a delicate and selective tool for the transfer of carbon nanomaterials. The simplicity of implementation of laser methods reduces the number of intermediate manipulations with the transferred material, increasing the safety of its structure. Here, we studied and implemented laser-induced blister forward transfer of high-quality graphene nanoribbons from a metal surface to a SiO 2 /Si substrate. We also studied the effect of the growth parameters and the transfer method on the structure of transferred carbon sites. The retention of the initial crystal structure of the transferred atomically precise graphene nanoribbons was confirmed by Raman spectroscopy.
