Microcomponents – measuring surface roughness

Researchers at the FEMTO-ST Institute in Besançon, France studied methods for fabricating lithium niobate ridges to be used for the development of programmable microcomponents.

Characterizing the silicon dangling bond

Bruno Grandidier, research scientist with the French National Center for Scientific Research (CNRS), reports on his work, focused on understanding the electronic properties of silicon dangling bonds.

Semiconductors: characterizing 3D structures at the nanoscale

Nanolithography is a precise patterning technology used to fabricate functional nanostructures for applications in biosensors, advanced materials and extensively in the semiconductor sector for solar cells, printed electronics, LED, MEMS, etc.

Understanding how Neolithic objects were manufactured

Tools for measuring surface roughness were used to study stelae and a menhir from the Late Neolithic-Chalcolithic period (around 3000 BC) discovered during the excavation of a prehistoric settlement in the Serra del Mas Bonet in Catalonia (Spain).

Failure analysis in optoelectronic devices

Quantitative cathodoluminescence technology coupled with the power of Mountains® software made it possible to localize and identify degraded layers in state-of-the-art green laser diodes.

Solar cell pyramids – visualization of 3D surface topography

Pyramid-shaped solar cells are particularly effective for converting energy from the sun into usable energy without the problem of overheating. In a study on solar cell performance enhancement, industrial researchers used Mountains® to visualize surface topography in 3D and overlay a color image of solar cells on topography.
