Abstract

The fabrication of gold microstructures was investigated using a mixture of SU-8 and gold ions using two-photon excitation induced by a femtosecond laser. Energy dispersive X-ray spectrometry, micro-X-ray diffraction and X-ray photoelectron spectroscopy were performed to analyse the resulting microstructures. Electrical conductivity was also measured. Elemental analysis showed that the fabricated structures consisted of triangular, reduced gold crystals and small amounts of cross-linked SU-8. The conductivity of the fabricated structures was four orders of magnitude lower than that of pure gold because of the cross-linked SU-8 present in the material.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
