Raman spectroscopy is being successfully applied to the analysis of a wide range of materials and systems.
Carbon and Nanotechnology:
You can use Raman to identify all the forms of carbon, including graphene, carbon nanotubes (CNT), graphite, diamond, and diamond-like carbon (DLC). You can also study 2D materials such as MoS2, hBN, and WSe2.The massive range of consumer products that use carbon-based materials—and the promise of 2D materials for future technologies—make these key application areas for Raman spectroscopy.
Analyse all the forms of carbon a) Renishaw's Raman systems are being used to research, develop, and control the quality of carbon materials. You can determine: the number of graphene layers, and their defects, doping and strain. Diamond Like Carbon (DLC) thickness and hybridised composition (sp2 and sp3), Carbon Nanotube (CNT) diameter and functionalisation, diamond stress, purity and origin (synthetic or natural), the properties of C60 and other fullerenes, the structural composition of amorphous carbons, Analyse monolayers and thin films. Some of the most interesting new materials consist of single, or just a few, atomic layers. The high sensitivity of Renishaw's Raman systems makes identifying and analysing them quick and easy.
Semiconductors :
Modern electronics use a wide range of semiconductor materials. Cutting edge devices, such as transistors, solar cells and light emitting diodes, push materials properties to their limits, and require extremely homogeneous source materials. Raman spectroscopy is an ideal tool for studying semiconductors.
Characterise semiconductors. You can use Raman to characterize and generate images of all semiconductors (e.g. Si, carbon-based, III-V's, and polymers) and superconductors. A wide range of information can be revealed, including: chemical composition (e.g. alloy fractions of compound semiconductors), polytypes (e.g. 4H-SiC and 6H-SicC), strain/stress, dopant concentrations, thin film thickness, crystal structure type and orientation, crystal quality, uniformity and purity, device temperature
Raman analysis is simple because it requires no sample preparation. It does not require vacuum technology, or suffer from charging effects experienced with electron microscopy.
PL Characterization: Raman systems also enable you to collect and analyse photoluminescence (PL) spectra. You can collect both vibrational and electronic information with one instrument.
Photovoltaics:
Raman spectroscopy is playing a leading role in the development of both existing and next generation photovoltaic technologies. It is not only used in research and development, but also to determine production quality.
Catalysis:
Raman spectroscopy is increasingly being used in the study of catalysts and catalytic reactions. This provides critical information on the mechanisms, helping to improve conversion efficiency.
Analyse a wide range of catalytic systems. Raman spectroscopy is particularly powerful for these studies:
1. Discriminate between multiple catalyst phases
2.Investigate reaction mechanisms
3.Conduct in situ measurements
Battery Technology:
Raman spectroscopy is an ideal tool for characterizing lithium-ion batteries, both for research and development. Renishaw's inVia confocal Raman microscope is perfect for studies ranging from fundamental work on the materials involved, through to final product quality control and failure analysis.
Identification of materials. InVia can analyse all the key material types: organic and inorganic; crystalline and amorphous; solids, liquids, and gases. Its high sensitivity makes identifying all the key battery components easy
