A research group led by Shunping Zhang and Hongxing Xu at Wuhan University, China, has developed a quantitative SERS technique to probe the maximum plasmonic fields before effects such as electron tunneling become dominant. The researchers turned to molybdenum disulfide (MoS2) — a graphene-like, two-dimensional atomic layer to tune the distance between a gold nanoparticle…
Femtosecond Laser Fabrication: Realizing Dynamics Control of Electrons
Femtosecond lasers are capable of processing any solid material with high quality and high precision using their ultrafast and ultra-intense characteristics. With the continuous development of laser technology, ultrafast laser manufacturing would hopefully become one of the primary methods employed in high-end manufacturing in the future. Recently, researchers realized a new method termed electrons dynamics…
