Reactive Ion Etching (RIE) Induced Surface Roughness Precisely Monitored In-Situ and in Real Time by Reflectance Anisotropy Spectroscopy (RAS) in Combination with Principle Component Analysis (PCA)

Advances in Materials Science and Engineering, 2022
Reactive ion etching (RIE) of group IV or III/V semiconductors is an important step in many lithographic processes in semiconductor technology. Typically, surface roughness is undesired, but more and more applications arise where rough surfaces are used ...

Experimental and Computational Aspects of Electrochemical Reflection Anisotropy Spectroscopy: A Review

ChemElectroChem, 2023
AbstractElectrode/electrolyte interfaces play a crucial role in many electrochemical energy conversion and storage technologies. Hence, a deep understanding of the interfacial structure, energetic alignment and processes is of high relevance and has triggered the development of a number of in situ and operando techniques.

The use of near infrared (NIR) spectroscopy to improve soil mapping at the farm scale [PDF]

, 2008
The creation of fine resolution soil maps is hampered by the increasing costs associated with conventional laboratory analyses of soil. In this study, near infrared (NIR) reflectance spectroscopy was used to reduce the number of conventional soil ...
