Our Capabilities
Surface chemical characterization of 2D materials
The surface of 2D materials, as well as their contact with the device substrate or package, is crucial due to their planar nature. Measurement methods with exceptionally high surface sensitivity and high spatial resolution are required to establish the chemical composition of these surfaces. Alfa Chemistry has unrivaled expertise in the chemical characterization of nano- and micron-scale surfaces and sub-surfaces, employing a variety of scientific methodologies to gain a better knowledge of materials.
Secondary ion mass spectrometry (SIMS) may offer extensive chemical information on inorganic and organic sample surfaces and sub-surfaces, and it can also be paired with high precision depth profiling. Other sections of a 2D device can be investigated using SIMS to generate 2D or 3D maps of impurities, contaminants, dopants, or surface functionalization. X-ray photoelectron spectroscopy is a supplementary approach for quantitative surface chemical investigation, such as detecting the thickness of organic pollutants or quantifying surface dopants.
Thin film surface chemistry characterization
Alfa Chemistry is the world's premier surface chemistry measurement laboratory, measuring 2D thin film material surfaces with precision. We provide essential standards, testing, and characterization methods for extracting relevant, usable, and accurate information on surface materials' chemistry, thickness, and placement. We've created improved methods for measuring chemistry in depth with great depth resolution and accuracy using materials.
Label-free chemical imaging
The surface chemistry of complex materials such as coatings, as well as the identification of crystalline phases and flaws, are studied using vibrational spectrum imaging. Based on molecular vibrations, Raman scattering can be used to measure and map chemical distributions inside a sample. Alfa Chemistry provides both spontaneous Raman spectroscopy and coherent Raman techniques such as Stimulated Raman Scattering (SRS) microscopy for non-destructive environmental analysis of a variety of sample types with low sample preparation needs. Raman scattering, both spontaneous and stimulated, produces signals that are linearly proportional to concentration, allowing for quantitative investigation.
