Major Applications of Microspectroscopy

One crucial area of progress is the examination of thin film semiconductors, where CRAIC's microspectroscopy approaches have allowed accurate assessments of film thickness, optical constants, and bandgap energy. By utilizing reflectance and transmittance microspectroscopy, scientists can now non-destructively assess these parameters with unparalleled spatial resolution. This has significant consequences for advancing next-generation semiconductor devices, where material uniformity and accurate optical properties are critical.

Moreover, CRAIC's microspectroscopy has aided the comprehensive study of semiconductor defects and impurities. The capacity to carry out localized photoluminescence and Raman spectroscopy at the microscale allows scientists to pinpoint and quantify faults that may impact semiconductor performance. This characteristic is especially helpful in the quality control of semiconductor wafers, where recognizing and reducing such flaws is essential for securing device reliability.

The combination of microspectroscopy with CRAIC’s advanced imaging systems has allowed the visualization of semiconductor heterostructures and interfaces. This has made the study of band alignment and charge transfer processes at these interfaces possible, helping design productive semiconductor devices like solar cells and transistors.
