Application

The Bismuth single crystal disc, with a diameter of 10mm and thickness ranging from 1-3mm, is crafted in a (111) crystallographic orientation and polished on both sides. This product serves as a crucial component in research and development applications where precise and high-quality bismuth surfaces are required. Its single crystal nature offers a consistent and reliable structure necessary for various scientific experiments, particularly in the field of condensed matter physics. The polished surfaces ensure minimal interference from surface irregularities, making it ideal for use in applications that require highly smooth surfaces. As an essential tool, it provides a stable foundation for investigating electronic properties and is an indispensable element in the study of material sciences.
