Our webinar presentation shows how a multi-technique approach using both Raman spectroscopy and XPS addresses the challenges posed at all steps in the creation of new graphene devices – from guiding the initial graphene synthesis, transfer to the desired substrate, and understanding chemical modification and analysis of the finished device.
A vibrational spectroscopy, the very high sensitivity of Raman makes it an ideal probe for a number of important properties specific to graphene and nanotube samples, such as layer thickness, sample integrity, and tube diameter.
X-ray photoelectron spectroscopy (XPS) is ideally suited to the determination of the surface chemistry and the way in which that chemistry changes in the surface and near-surface region. The technique provides quantitative elemental and chemical information with extremely high surface specificity and is ideal for comprehensively and quantitatively characterizing the elemental composition and chemical bonding states in graphene and carbon nanotubes.
Our webinar demonstrates how using both techniques in concert allows analysts to completely characterize carbon nanomaterials as illustrated by examples from graphene samples created by mechanical exfoliation, chemical reduction and CVD methods.
Areas of Interest:
X-ray photoelectron spectroscopy delivers chemical state information from the topmost few nanometers of the surface of a sample. Modern instruments, such as the Thermo Scientific™ K-Alpha™+ XPS system, can extend analyses into chemical images of the surface, revealing the extent of surface modification, or allowing defect detection. These strengths allow scientists and engineers to measure the effectiveness of coatings, understand plasma modification processes, and develop bio-compatibility coatings.
