Direct Synthesis of Printable 2D Material Inks Using LASiS

The proposed work demonstrates a novel method to directly synthesize both novel 2D materials and doped 2D material. In our technique, we use laser ablation of a sample in solvent to directly generate inks compatible with printing tools for the development of flexible electronic fabrication. 2D sheets of galfenol (gallium-iron alloy) doped with graphene and molybdenum disulfide (MoS
2
) are created through direct femtosecond laser ablation without the need for chemical precursors or bulky equipment. The 2D materials produced show promising results for the ability to be printed, for example using an aerosol jet printer (AJP), without any post-processing.
