Applications

Semiconductors and Microelectronics

Solar cell manufactures have a keen interest in a qRICO device. Crystallographic orientation analysis is a critical step in the development of efficient solar cell panels. Existing analytical techniques (EBSD, XRF, etc.) for two-dimensional crystallographic analysis are too expensive and too limiting in their capabilities to be routinely used in an industrial environment. Similarly, strong needs exist in the semiconductor device and process monitoring market to deliver crystallographic analysis both in process development applications and also for quality control purposes. A qRICO device will be uniquely suited for fulfilling the demands in these areas.

Dislocations and Stress in Electronics

Inhomogeneities and dislocations in heterostructured semiconductors with high levels of local heating in operation conditions can greatly reduce the lifetime of devices like LEDs and laser diodes. Therefore, nano- and microscale orientation mapping of such structures by qRICO can provide important information in the development and quality control of devices.

2D Materials

qRICO has a great potential of quantitative orientation mapping in 2D materials. It can be used for orientation determination and dislocation search of separate layers in multi layered 2D materials.

Ceramics

3D grain mapping is very important in ceramics technology, because properties such as fracture strength is strongly influenced by the statistical distribution of grain orientation and the grain boundary topology. Thus qRICO can provide unique information in piezo-, magneto-, and ferroelectrics.

Superhard Materials

Abrasives, drilling tools, superhard transparent windows – all mentioned examples require the knowledge of crystallographic orientation of poly-crystalline surfaces.

Crystalline Drugs and Proteins

Raman microscopy is often used for chemical mapping of pharmaceutical materials. It has been shown that polarized Raman microscopy can be used to visualize particles on the surface of tablet formulations, however so far no quantitative information on the orientation of single particles has been provided. We demonstrated successful Raman measurements of a content nonuniformity in a tablet containing carbamazepine dihydrate (CBZD) and polyvinylpyrrolidone (PVP). Using multivariate curve resolution (MCR), these components were decomposed including the fluorescence background as shown in Figure on the left. Applying qRICO to the same area on the surface of the tablet, we obtained an orientation map of CBZD (monoclinic symmetry, C2h crystal class). These findings show the potential for qRICO to provide insight into crystal face functionality in pharmaceutical research as well as in materials science.
