Earlier this month, Alfa Chemistry, one of the world’s leading chemical suppliers, announced the launch of a comprehensive range of pure element single crystals. These chemicals are produced in various dimensions for applications in semiconductors, lasers and nonlinear optics, detectors, monochromators, basic research, as well as many high-end technology scenarios.
Featuring higher purity and fewer defects than common polycrystalline materials, single crystals are essential for research, especially in condensed-matter physics, material science, and surface science. In addition, single crystals are a prerequisite for performing techniques such as scanning, tunneling, or microscopies.
“Our offering of pure element single crystals aims to play a role in pushing forward the creation and development of more advanced materials that would be suitable for applications in various fields,” said a representative from Alfa Chemistry. “They can be tailored almost into any geometric shape, size, and crystalline orientation according to customer needs.”
The pure element single crystals that are currently available include Si, non-ferrous metals like Cu, Zn, Co, Cr, and Ni, rare metal such as Ru, Ta, Nb, In, Ge, and V, and precious metals like Au, Ag, Pt, and Pd, as well as the transition metal. Below are some of the pure element single crystals provided by Alfa Chemistry:
