Copper Square Single Crystal

Copper Square Single Crystal consists of a continuous copper lattice free from grain boundaries, precisely oriented and cut into a square geometry to ensure uniform physical and chemical properties. This single-crystal structure delivers exceptional electrical conductivity, high thermal transfer efficiency, and consistent mechanical behavior, making it ideal for advanced research and manufacturing. It is used extensively in electronics, surface science, and precision deposition technologies, including sputtering targets for microelectronic fabrication, substrates for epitaxial growth, and catalysts for selective reactions. Technologies benefiting from this material include semiconductor interconnect studies, thin-film growth of functional materials, and controlled surface modification experiments. In research, it offers a defect-free platform for investigating electron transport, corrosion mechanisms, and crystallographic surface phenomena. Its value in science and industry lies in its ability to deliver unparalleled consistency and performance where purity, stability, and reproducibility are critical.
