Compound materials enable the production of advanced, easy-to-use power devices, ultra-high frequency radio devices and more. These emerging products become more and more prevalent in electric or hybrid cars for example, or in power management and distribution devices related to renewable energy sources. For reliable production, composition and defects, dopant concentration, electrical and optical qualities must be regularly monitored. Semilab offers several products for this purpose. Most products are non-contact and non-destructive, and in many cases, they reveal properties directly related to device characteristics or performance.
