Gold Square Single Crystal
Gold Square Single Crystal is one of 29 variations offered in Goodfellow's range of single crystals. Single crystals like these are integral to research across physics, chemistry, and materials science. Their highly ordered atomic structure and purity enable precise analyses of materials properties. For example, oriented gold single crystals can selectively reflect or transmit specific wavelengths when used as monochromators or analyzers in x-ray and neutron diffraction. The lack of grain boundaries also makes them ideal choices for electrodes probing electrical transport phenomena. With 29 orientations available, Goodfellow's Gold Square Single Crystals provide researchers flexibility in designing experiments probing the intrinsic properties of this noble metal.
