Compound semiconductors are used everywhere! We rely on them every day, from the simple things such as a computer mouse and laser printer, to advanced applications such as LIDAR (laser imaging, detection, and ranging) and autonomous driving. Regardless of the end product, planning and research in the early stages of product development can help to maximize performance and decrease the probability of failures in the future.
The structural and compositional uniformity during epitaxial growth of compound semiconductors is critical for developing reliable and efficient devices. Many different types of defects and non-uniformities can occur during growth which can hinder final device performance. Therefore, it is very important to assess epitaxy quality before device fabrication steps. EAG can help!
During epitaxial growth, an issue in a single layer can affect the entire structure of a device causing non-uniformities in thickness and composition. AC-STEM with EDS can be utilized to understand epitaxial variations that span from the nanoscale to the atomic scale during growth.
AC-STEM imaging is essential towards studying these types of fine sample features because bulk techniques lack the necessary spatial resolution. By combining this type of analysis with other Eurofins EAG services such as SIMS, it is possible to gain a clear understanding of the epitaxy structure and composition with atomic scale resolution and dopant level composition sensitivity.

For 3D printed products, XPS can provide composition and bonding information for the top 5-10nm sample surfaces. Oftentimes, surface contamination/oxide thickness would affect the appearance (as well as performance when applicable) of the material, and XPS could help identify the source and/or cause.
As medical devices become more complex, there are many more opportunities for things to go awry. Identifying, diagnosing, and remedying failures becomes dramatically more challenging. We can help.
Composition can play a critical role in the performance of a 3D printed product. It’s good to know that analytical testing can help verify elemental composition.
Product liability cases have many complexities and challenges and require top-notch legal services. Navigating the intricate details of these cases requires not only legal insight but also specialized expertise in various technical and regulatory domains.
