Application

The Bismuth single crystal disc, measuring 10mm in diameter and 1-3mm in thickness, is designed for applications that require precise control of electrical and thermal properties. Bismuth, known for its non-toxic nature and low thermal conductivity, serves as an ideal material in research and industrial applications where these characteristics are essential. This single crystal form provides uniformity and predictability in its behavior, making it valuable for experimental setups or components in specialized devices where performance consistency is crucial. Additionally, its unique properties make it suitable for studying phenomena such as magnetoresistance or for use in thermoelectric devices where efficiency and reliability are paramount.
