Ph.D. Thesis: Scanning Microscopy and Momentum-Resolved Raman Scattering in Semiconductors and Oxides
In his Ph.D. thesis, Nitin Chelwani worked on Raman scattering on correlated electron materials and setting up tip-enhanced Raman scattering at WMI. In particular, he developed a set-up for tip-enhanced Raman spectroscopy and performed a comparative study of the Raman response of three CuO2-based compounds as prototypical spin 1/2 antiferromagnets. As a major innovation of the optical configuration he used an an off-axis parabolic mirror and explored in detail the advantages and potential challenges of this configuration. The symmetry-resolved spectra measured in his thesis indicated that the line shape in B1g symmetry is universal and independent of the excitation energy.
After leaving WMI, he joind Bruker Optics (Research & Development Optics - Infrared Spectroscopic Solutions).
