A Gold Single Crystal Substrate is a high-performance substrate material fabricated from a single crystal of gold. Unlike polycrystalline materials, single-crystal substrates feature a uniform crystal lattice without grain boundaries, resulting in superior electrical, thermal, and mechanical properties. These attributes make gold single-crystal substrates indispensable in high-precision applications such as electronics, photonics, and advanced materials research.
Stanford Optics employs the Modified Bridgman method to grow gold single crystals along the <111> direction, achieving diameters of up to 20 millimeters. The Gold Single Crystal Substrate is meticulously cut from the gold ingot and polished to a surface roughness of 30 Å (angstroms), ensuring optimal performance in demanding applications.
Our Gold Single Crystal Substrate is carefully handled during storage and transportation to maintain the pristine quality and structural integrity of the single crystal. Each substrate is packaged in protective materials to prevent contamination and physical damage, ensuring that the exceptional properties of the substrate are preserved until use.
