A team of researchers from Finland’s University of Jyväskylä and Serbia-based University of Novi Sad suggest that ultrafast laser processing can help us unlock the potential of 2D materials.

Some 2D materials such as graphene, silicene , black phosphorus, and transition metal dichalcogenides are electrically and mechanically superior to others.

However, currently, scientists don’t have the perfect technique to manipulate and process these 2D materials, and this prevents us from harnessing their potential. However, findings from a new study reveal a solution to this problem. However, both continuous wave and long-pulse methods have one big limitation. When light strikes a material continuously in the form of waves or energy bursts, it results in the generation of heat which if not properly managed can damage the material. It can make changes in materials at the nanoscale.
